STERNPERCH SAILBOAT SEATS
Stern Perch seats make older sailboats like new!
One of the biggest complaints among owners of pre-1993 sailboats is the absence of the popular stern rail seats. Now you can add them to many of the older model boats! They're custom designed for a perfect fit, yet easily removed if you need them off.
Made from 1/2" marine-grade polymer, our stern rail seats are easy to install (no tools are required). When installed, the seat attaches to the lower stern rail and lies inboard of it. (An upper and lower stern rail configuration is required.) The seats are supported from the stern pulpit as well as a leg which rests on the deck, coaming, or cockpit of the boat (location varies depending on boat design). The entire seat is designed to tilt up for access to hatches or other deck fittings if necessary. Recommended weight limit is 250 lbs. per seat.
We've sold a great number of the seats and owners have been quite happy with them. Each set includes built-in drink holders, too!
Consider Rail Cushions and or Lifeline Cushions for added comfort on your back when leaning against the stern rail.

BENNETT TRIM TABS M80 SPORT TAB SYSTEM
Bennett Trim Tabs are designed and manufactured with pride at the Bennett Marine plant in Deerfield Beach, Florida. Every Bennett system carries with it an accumulation of nearly 40 years of research, development, and testing and is designed to provide years of dependable service.
Every trim tab is sheared and bent, not welded. Welding alters the properties of stainless steel which invites corrosion. Bennett actuators feature through-hull hydraulics. There are no vulnerable external hoses to decay. Plus, every Hydraulic Power Unit is tested by both person and computer to insure this reliable unit deflects the trim tabs, holds firmly during use, and retracts smoothly.
Sport Tabs
Bennett's M80 and M120 Sport Tabs are ideal for trailered boats in the 17-foot to 23-foot range. Their unique Batwing design provides 30 percent more lift than conventional trim tabs and their space-saving design ensures easy installation on virtually any transom. Trim tab kits include two stainless steel trim tabs, two actuators, a hydraulic power unit, all necessary wiring, tubing, hardware and installation video.

ICOM AT-130 HF AUTOMATIC ANTENNA TUNER
HF Automatic Antenna Tuner
Tune in your HF marine world
Suitable for many vessels
The versatile AT-130 can be used with a variety of vessels, even smaller boats that cannot use a long antenna element. For example, the AT-130 will match a 7 m (23 feet) long wire antenna across the marine band in the 1.6 - 27.5 MHz range.
Automatic tuning
No manual tuning is needed. Just push the [TUNE] switch on an Icom HF marine transceiver; the AT-130 adjusts the antenna and the transceiver to the minimum SWR in any frequency on an HF marine band. The AT-130 allows you to transmit with strong RF output power, and is perfect for maritime mobile operations.
Weather resistant
The AT-130 is housed in a durable, completely weather-resistant acrylic case with rubber gaskets. This allows it to be conveniently installed near the antenna element base.

Shipboard Electronics and Communications Systems
Electronics and communications systems for your boat:
• What components are there, what are their advantages and what should I look for?
• Are different brands compatible?
• What communications do I need and what is the difference?
• The importance of quality antennas.
Marine electronics are in many ways, like household computers in that they are not the be all and end all of our navigation needs, we will not sail off the end of the earth without one, there are countless brands with everyone claiming to have the latest and the greatest and it always seems the minute you buy something there is a newer model or upgraded software! However, marine electronics do make our boating life easier and in certain cases a lot safer. Some of the most common and popular types of electronics are:
• Direct sunlight view ability: many chartplotter displays can be very difficult to view when using it in a bright sunny environment or when the sun directly shines upon the display. It is always best to try and view a chartplotter display in a bright environment to get an idea or talk to people with what experiences they have had;
• Single or multifunction capability: most of the mid range to high end chartplotters on the market have multifunction capability meaning they have the functionality to operate as a chartplotter / GPS as well as a sonar / depth sounder, a radar (this multifunction is very useful for doing a radar overlay over the chart making navigation in unfamiliar areas at night far easier and safer), video inputs for running deck and engine room cameras and VGA outputs for sending the chartplotter information to a TV or PC just to name a few. However, for those of you who like the security of having separate chartplotter, fishfinder and radar units in case of a display failure and all information being lost, you can purchase these systems individually;
• Do you wish to run more than one screen?: It is becoming increasingly common to see more than one screen being used on a boat, particularly on dual station boats, fishing boats and larger yachts with a separate helm and navigation areas. In these cases, look for a chartplotter which has network capability. Certain units such as the Raymarine E series and the Garmin 5008/5012 series can run up to five separate displays off the same network using only radar and sounder module/transducer. It’s a good idea to take future expansion into consideration as a non networkable unit will have to be replaced if additional screens need to be added later. Pay now, save later as they say!;
• Screen size: this is an interesting one as most of the time we are limited to what will fit either flush mounted or gimble mounted on our dash board. However when there is ample room, I always recommend to my clients that they go for as large a screen as possible. The reason for this is simple. When looking at electronic charts, it is far easier to read something when it is bigger, this is especially the case when navigating in rough water and we are being thrown around. The same applies if operating a mutilfunction unit in a split screen mode with several different pieces of information being displayed. A chart and a radar are near impossible to read when we are on a higher range and items of information can easily be overlooked.
• NMEA 0183 and NMEA 2000 compatible: we will talk about these a little later in this article;
• Easy to use menus and function keys: whilst this is a very personal choice, my recommendation is to play with the unit before purchasing to find out what you like. As technology is progressing, we are getting more and more functions all the time. Some manufacturers such as Garmin have taken ease of use to new levels with the new touch screen displays and the unique Auto Guidance system which allows you select a destination and then the unit will plot a course through navigation markers whilst staying within your boats’ set safe depth and height limits.
• Software upgrades: this is something that is often taken for granted. Some manufacturers actually post their software upgrades on their websites. These upgrades can be downloaded onto an SD Card and then uploaded to the GPS chartplotter. Many of these upgrades can include additional features, improved menus and improved system performance. Whilst purchasing a unit which can not be easily upgraded may be cheaper, the downsides are the unit will date quickly and may end up being incompatible with component upgrades and future additions.
It has to be said that digital technology has dramatically improved the performance of this technology. Comparing an old fishfinder to a new digital one is like comparing the picture quality of an old VHS video player to the latest DVD player.
A depth sounder / fishfinder / sonar works by a transducer converting electronic impulses from the fishfinder to sound waves, which then travel down through the water at about 4,800ft per second, regardless of frequency. When the sound waves bounce off the bottom or a fish, the returning echo is picked up by the transducer, which converts it back to electrical impulses. These impulses are then converted by the fishfinder into a picture of the bottom and, hopefully, fish. The higher the frequency of the impulse, the more detailed the resolution. For deep sea fishing, a lower frequency transducer may be a better choice, since it can be used at greater depths.
When selecting a depth sounder / fishfinder / sonar many of the features we need to look at are the same for the GPS chartplotter. However in this instance, the most important factor is the transducer selection and there are several choices available:
Transducers
• Transducer composition – transducers are made of varying material types to suit different hull composition:
- plastic transducers - suitable for fiberglass or metal hulls
- bronze transducers - suitable for fiberglass or wood hulls
- stainless steel transducers - suitable for steel or aluminum hulls
• Transducer type – there are three basic types of transducers:
- Thru-Hull Transducers
These are mounted through a hole drilled in the bottom of the boat and protrude directly into the water. This type of transducer generally provides the best performance. Thru-hulls are recommended for displacement hulls and boats with straight-shaft inboard engines. You will also need a fairing block to enable the transducer to be mounted properly. Thru-hull transducers must be installed with a fairing block to ensure proper alignment and a secure fit.
- In-Hull (also commonly known as Wet Box or Puck transducers) Transducers
These are mounted directly on the inside of the hull. These are only used in fiberglass hulls. In-hulls will not work with wooden aluminum, wood, or steel hulls, or in foam sandwich or hulls that have air pockets. Any wood, metal, or foam reinforcement must be removed from the inside of the hull for an in-hull to operate effectively. With an in-hull transducer, the signal is transmitted and received through the hull of the boat. As a result, there is considerable loss of sonar performance. In other words, you won’t be able to read as deep or detect fish as well with an in-hull transducer as with one that’s transom mounted or thru-hull mounted. These are popular transducers with sport cruisers and yachts where high performance is not critical and the fact that drag in the water is also reduced.
- Transom Mount Transducers
These are installed on the boat’s transom, directly in the water and typically sticking a little below the hull. Transom mounts are composed of plastic and tend to be less expensive than other transducers. Transom mount transducers are recommended for planning hulls under eight meters and trailer boats, such as powerboats with outboard, inboard-outboard and jet drives. They are not recommended for large or twin screw inboard boats because aerated water from the propeller reduces performance. They are also not suitable for boats which are permanently in the water as transducer life and performance is compromised over time.
The main features of transducers that you should consider are:
• Transducer Power – power refers to the strength, with which the transducer sends the sonar ‘ping’, expressed as watts RMS. Higher power increases your chances of getting a return echo in deep water or poor water conditions. It also lets you see what’s under the boat in better detail, such as bait fish and structure. Generally, the more power you have, the deeper you can reach and the easier it is to separate echoes returning from fish and bottom structure from all the other noises the transducer detects. Most sport cruisers, yachts and cruisers will generally find 600W more than enough power, while sport fishers and game fishing boats will generally have a minimum of 1kW with many game boats using 2kW or even 3kW transducers for the best possible performance when looking for canyons off the shelf.
• Transducer Frequency – today most transducers over 600W are dual frequency meaning that the transducer has the ability to look at high and low frequencies at the same time. 50/200 kHz is by far the most common in transducers however in upper end 1kW plus transducers 28/200 and 38/200 kHz is also common.
Basically the differences in frequencies can be explained as follows:
- 200 kHz is the best option in water under 200ft/60m if you need to get an accurate reading while moving at faster speeds. High frequencies give you greater ability to detect very small objects but over a smaller portion of water. High frequencies typically show less noise and fewer undesirable echoes while showing better target definition.
- 50 kHz is the best option for deep water. This is because water absorbs sound waves at a slower rate for low frequencies and the signal can travel further before becoming too weak to use. The beam angle is wider at low frequencies, meaning the outgoing pulse is spread out more and is better suited for viewing a larger area under the boat. However, this also means less target definition, separation and increased susceptibility to noise. Although low frequencies can see deeper, they may not give you a clear picture of the bottom.
Mud, soft sand, and plant life on the bottom absorb and scatter sound waves, resulting in a thicker bottom image. Rock, coral and hard sand reflect the signal easily and produce a thinner bottom display. This is easier to see using the 50 kHz setting, where the bottom returns are wider.
Radar Stand Along Units and Domes and Arrays
Radar is an acronym meaning Radio Detection and Ranging. It is a device which not only measures the time it takes for a pulsed signal to be reflected back from an appropriate object, but also determines its bearing relative to your position. Once the time and bearing are measured, these targets or echoes are calculated and displayed on your radar display. This will give you a bird’s eye view of where other targets are relative to you, even when you cannot see them with your eyes due to low visibility.
What can radar do for me? With radar acting as your eyes, you have the ability to see objects (targets) such as landmasses, weather systems and other vessels to assist you in the navigation of your vessel.
There are many things to consider when buying radar. Here are a few:
• Boat Size – radars are available in various sizes and configurations. The most popular are Radom’s and open array scanners. Radom’s are the most popular configuration due to their compact size, lower power consumption and lower purchase price. Open array scanners are popular with larger vessels because of their increased performance due to the narrower beam angles, higher transmitting power and better target definitions.
• Transmitter Power Output – a higher power output level increases the radar’s ability to receive signals reflecting off objects and show them as targets on your display. Higher-powered radar also has greater capacity to ‘punch through’ fog and precipitation, allowing you to see objects around your vessel.
• Beam Angle – this specification is related to the length of your antenna. The longer the antenna is, the narrower the beam angle. This narrow beam angle increases the radars bearing resolution allowing you to discriminate easily between two objects that are close together. It also shows land mass contours and inlets with much greater resolution.
Can I navigate with radar? Fishing vessels and pleasure boats commonly use radar to help them navigate to their favorite fishing spots. When heading to a particular spot, the forces of wind and current combine to shift the vessel off its intended course. To determine your position and to counter vessel drift, use the VRM (Variable Range Marker) and the EBL (Electronic Bearing Line) to mark range and bearing to fixed targets.
Autopilots
For any passage making boat or yacht, an autopilot is a necessity. The thrill of steering a boat on the open ocean is quickly diminished when one realizes how tiring it is especially if there are many more hours ahead. An autopilot gives you the ability to accurately navigate to a point without having to touch the helm. In many ways an autopilot especially if fitted with a rate gyro and interfaced with a chartplotter can out steer and navigate a straighter course than even the most seasoned skipper (and it doesn’t get hungry or thirsty!).
Autopilots comprise of several main components:
• The Head Unit – this is the controller for the autopilot. Every manufacturer has different styles to suit various applications and tastes. Many can have multiple stations and be wireless giving the skipper the ability to tend to lines and rigging while underway or just sit on the deck and enjoy the surroundings.
• The Course Computer – this is the brains of the autopilot. It basically takes the information from its sensors/GPS chartplotter and tells the drive unit which way to steer the boat.
• The Drive Unit – this creature steers the Rudder, sterndrive or outboard. There are several types or drive units with the most popular being hydraulic drive (for hydraulic steering), rotary drive (for chain steered yachts), linear drive (for mechanical steering), wheel drive (attached to the helm wheel) and tiller drive (attached direct to the tiller).
• The Rudder Angle Indicator – This device tells the course computer what position the rudder is, thus allowing the course computer to calculate how much rudder or counter rudder needs to be applied.
When selecting an autopilot you first need to select your drive unit to suit the steering mechanism of the boat. Secondly, select a course computer/corepack. This is sized to the boats size and weight. The key point here is not to undersize a system for when the seas are rough, you do not want the system struggling and or worse, failing. The final step is to select a head unit to drive the system.
You quickly realize how useful an autopilot is when correctly sized and installed.
Interfacing
Most modern marine electronics now support either NMEA 0183 or NMEA 2000 which are combined electrical and data specifications for communication between marine electronic devices such as fish finders, autopilots, GPS receivers, engine data and many other types of instruments. NMEA communicates via data sentences between devices which support either 0183 or 2000 so that different brands can be used in a system. In most cases this is perfectly fine, however if any of the data (check sums) is different than certain functions may not work between the two devices.
If you want the best reliability in a system between devices, it is often best to stick with the one brand throughout, from both an aesthetic and resale perspective.
COMMUNICATIONS
Marine radios are essential safety equipment for communicating with other boats, marine rescue groups and to receive navigational warnings and weather updates. There are three types of marine radios:
VHF - the VHF radio remains the most versatile communication device for a boat and is often the only communication device most pleasure boats carry. Due in part to its versatility , the VHF is arguably the most valuable piece of safety gear aboard, delivering any call for assistance to dozens or hundreds of nearby listening ears
Fixed Mount or Hand-Held - modern hand-held VHF radios are full featured, extremely convenient, and they have the significant advantage in an emergency of being independent of the boat's electrical system. Where maximum range and/or continuous use are more important, you will want a fixed-mount unit. If your budget allows, having both offers additional advantages, such as two-way communications with an excursion party (but note, transmissions from ashore is prohibited without a coast-station permit).
The VHF radio is NOT a telephone
Boaters often use the VHF much like a telephone to call other boats and shore stations to relay information, to make appointments, or sometimes just to chat. Before you join in, however, you should recognize the differences between VHF radio and telephone communication: Radio conversations are not private. When you talk on the VHF, everyone within range tuned to that channel is listening. A radio conversation ties up the channel you are using. No one else up to a 25 mile radius can use it until you release the transmit button on the microphone.
Use of low power
All fixed-mount VHF radios can transmit at either 25 watts or 1 watt. The maximum power from a handheld is typically 5 watts. With either type, if your radio contact is nearby, set the power setting to low (1 watt) to reduce the distance the signal carries beyond your target. Also watch your language; not only is profanity over the air against the law, it will be particularly offensive to other boaters with children aboard.
HF Radio
HF Radios have a greater communication range if travelling long distances from shore. Queensland HF services cover coastal waters to a minimum of 200 nautical miles seaward from sites located at Cairns and Gladstone. These Stations maintain 24 hour listening watches on 4125 kHz, 6215 kHz and 8291 kHz for distress and safety situations. It is important to restrict radio traffic on these frequencies to distress, safety and urgency calls. The 'Coast Radio' Stations will also broadcast navigation warnings on 8176 kHz.
HF radios are expensive to purchase, they require far more experience to operate than a VHF as you have to tune them in and they also require careful consideration with installation as earth plates, grounding straps, antenna tuners, deck insulators and special antennas will be required. If not installed correctly radio performance can be severely hampered as HF radios are very prone to electrical interference. Cost is install is also far greater than that of VHF.
If you are venturing far off the coast then a HF Radio is a good investment as it offers a far superior range than a VHF radio and it also offers more security than a Satellite phone. You can only call one person on a Satellite phone where as you can reach many people in one call with a HF radio.
Both VHF and HF radios require the operator to obtain a Marine Radio Operators Certificate of Proficiency (MROCP), which covers the operation of both VHF and MF/HF equipment. The Marine Radio Operators VHF Certificate of Proficiency (MROVCP) has a somewhat simpler syllabus, but only covers the operation of VHF equipment. Most coast guard, VMR and certain yacht clubs will run these courses though out the year.
Antennas
Knowledgeable boaters realize that even the most expensive radio will perform poorly with a second rate antenna that may well save you money up front, but may jeopardizes the welfare of those aboard in time of need. That’s why we prefer the quality, performance and reliability of Shakespeare marine antennas.
Shakespeare fiberglass antennas are built with precision, beginning with hand-soldered connections, brass and copper elements, strong mechanical joints and superior electronics. The radiator and electrical elements are then encased in an exclusive Shakespeare fiberglass radome.
Tips on choosing the proper antenna
Since there are many factors that influence the selection of a proper antenna for a specific application, we encourage consultation with a local dealer, whenever possible.
When this is not possible, the following tips should be considered before making a final decision.
• Antenna Length – height is paramount in getting the greatest range, and encourages the selection of an antenna that can be placed as high as possible on the boat.
• Sailboats – as a general rule, sailboats have a 3’-5’ antenna mounted on the masthead. Some racing enthusiasts opt for an 8’ antenna mounted on the stern in the event demasting should occur. Either is acceptable. A decision should be made on personal preference.
• Powerboats – most power boats from 16’ to 25’ in length use a standard 8’ antenna, while bigger vessels have the option of larger antennas with more gain. Caution: be sure to allow enough lay down room for clearing low bridges or other limitations. Whichever choice is made, a sturdy mounting arrangement must be used to avoid damage to both boat and antenna.
• Gain ¬– this is a rating stated in decibels (dB). Generally, the higher the gain, the greater the communicating range. However, keep in mind that the higher the gain, the more compressed the beam width becomes. A narrow beam can cause fading in rolling seas. Small, lightweight boats, which roll excessively in heavy seas, normally do not use a gain rating above 6dB. The more stable the platform of a vessel, the higher the gain that can effectively be used.
• Mounts – be sure to pick the mount style that will best support the antenna on a particular boat. When using a two-piece antenna system greater than 10’ in length, an upper support clamp is necessary. For antennas of 14’ to 18’, the upper clamp should be 3’ to 5’ from the bottom. For antennas of 18’ to 23’, the upper clamp should be 4’ to 8’ from the bottom. Positioning the upper clamp too high or too low can significantly increase the potential for structural failure.
• Cable – RG-58 cable is sufficient for cable runs up to 20’. For runs over 20’, larger and better, low loss RG-8/X, RG-8A/U or RG-213 are preferable. Shakespeare uses Low loss, UV stable RG-8/X throughout its Galaxy antenna line. Today’s enhanced cellular services, which operate in the 1800-1900 MHz range place even more importance on using a high quality coax. That’s why Shakespeare developed its exclusive Lo-Max® cable for dual band cellular antennas. Its low loss characteristics are near those of larger RG-8A/U and RG-213 cables, without the extra bulk and rigidity. For optimum performance from your VHF, HF/SSB and cellular communications systems, the cable should be kept as short as possible. Caution: cable supplied with some antennas may not be cut or altered. Be sure to check the instruction sheet before attempting to shorten the cable.
• Low Angle Radiation – Shakespeare pioneered low angle techniques in marine antennas in the 1960s and built them into many models. Low angle minimizes fading while maximizing range even during excessive boat roll in turbulent seas. A normal angle shortens the range and wastes power.
The greatest tip to keep in mind is that no matter how much you pay for your radio, its performance will be directly proportional to the quality and performance capabilities of the antenna. Don’t compromise ... insist on a genuine Shakespeare Antenna.
As you can see there is so much to take into consideration when planning your electronics and communications and we have not talked about other devices such as AIS, wind instruments, forward looking sonar’s, Deck cameras, thermal imaging cameras ... and the list goes on. I recommend that you start planning what you want to put on your boat but hold off on purchasing until you are ready for installation so that way you get the latest versions and are confident about compatibility and functionality.

Certain units such as the Raymarine E series and the Garmin 5008/5012 series can run up to five separate displays off the same network using only radar and sounder module/transducer. It’s a good idea to take future expansion into consideration as a non networkable unit will have to be replaced if additional screens need to be added later. Pay now, save later as they say!;
• Screen size: this is an interesting one as most of the time we are limited to what will fit either flush mounted or gimble mounted on our dash board. However when there is ample room, I always recommend to my clients that they go for as large a screen as possible. The reason for this is simple. When looking at electronic charts, it is far easier to read something when it is bigger, this is especially the case when navigating in rough water and we are being thrown around. The same applies if operating a mutilfunction unit in a split screen mode with several different pieces of information being displayed. A chart and a radar are near impossible to read when we are on a higher range and items of information can easily be overlooked.
• NMEA 0183 and NMEA 2000 compatible: we will talk about these a little later in this article;
• Easy to use menus and function keys: whilst this is a very personal choice, my recommendation is to play with the unit before purchasing to find out what you like. As technology is progressing, we are getting more and more functions all the time. Some manufacturers such as Garmin have taken ease of use to new levels with the new touch screen displays and the unique Auto Guidance system which allows you select a destination and then the unit will plot a course through navigation markers whilst staying within your boats’ set safe depth and height limits.
• Software upgrades: this is something that is often taken for granted. Some manufacturers actually post their software upgrades on their websites. These upgrades can be downloaded onto an SD Card and then uploaded to the GPS chartplotter. Many of these upgrades can include additional features, improved menus and improved system performance. Whilst purchasing a unit which can not be easily upgraded may be cheaper, the downsides are the unit will date quickly and may end up being incompatible with component upgrades and future additions.
It has to be said that digital technology has dramatically improved the performance of this technology. Comparing an old fishfinder to a new digital one is like comparing the picture quality of an old VHS video player to the latest DVD player.
A depth sounder / fishfinder / sonar works by a transducer converting electronic impulses from the fishfinder to sound waves, which then travel down through the water at about 4,800ft per second, regardless of frequency. When the sound waves bounce off the bottom or a fish, the returning echo is picked up by the transducer, which converts it back to electrical impulses. These impulses are then converted by the fishfinder into a picture of the bottom and, hopefully, fish. The higher the frequency of the impulse, the more detailed the resolution. For deep sea fishing, a lower frequency transducer may be a better choice, since it can be used at greater depths.
When selecting a depth sounder / fishfinder / sonar many of the features we need to look at are the same for the GPS chartplotter. However in this instance, the most important factor is the transducer selection and there are several choices available:
Transducers
• Transducer composition – transducers are made of varying material types to suit different hull composition:
- plastic transducers - suitable for fiberglass or metal hulls
- bronze transducers - suitable for fiberglass or wood hulls
- stainless steel transducers - suitable for steel or aluminum hulls
• Transducer type – there are three basic types of transducers:
- Thru-Hull Transducers
These are mounted through a hole drilled in the bottom of the boat and protrude directly into the water. This type of transducer generally provides the best performance. Thru-hulls are recommended for displacement hulls and boats with straight-shaft inboard engines. You will also need a fairing block to enable the transducer to be mounted properly. Thru-hull transducers must be installed with a fairing block to ensure proper alignment and a secure fit.
- In-Hull (also commonly known as Wet Box or Puck transducers) Transducers
These are mounted directly on the inside of the hull. These are only used in fiberglass hulls. In-hulls will not work with wooden aluminum, wood, or steel hulls, or in foam sandwich or hulls that have air pockets. Any wood, metal, or foam reinforcement must be removed from the inside of the hull for an in-hull to operate effectively. With an in-hull transducer, the signal is transmitted and received through the hull of the boat. As a result, there is considerable loss of sonar performance. In other words, you won’t be able to read as deep or detect fish as well with an in-hull transducer as with one that’s transom mounted or thru-hull mounted. These are popular transducers with sport cruisers and yachts where high performance is not critical and the fact that drag in the water is also reduced.
- Transom Mount Transducers
These are installed on the boat’s transom, directly in the water and typically sticking a little below the hull. Transom mounts are composed of plastic and tend to be less expensive than other transducers. Transom mount transducers are recommended for planning hulls under eight meters and trailer boats, such as powerboats with outboard, inboard-outboard and jet drives. They are not recommended for large or twin screw inboard boats because aerated water from the propeller reduces performance. They are also not suitable for boats which are permanently in the water as transducer life and performance is compromised over time.
The main features of transducers that you should consider are:
• Transducer Power – power refers to the strength, with which the transducer sends the sonar ‘ping’, expressed as watts RMS. Higher power increases your chances of getting a return echo in deep water or poor water conditions. It also lets you see what’s under the boat in better detail, such as bait fish and structure. Generally, the more power you have, the deeper you can reach and the easier it is to separate echoes returning from fish and bottom structure from all the other noises the transducer detects. Most sport cruisers, yachts and cruisers will generally find 600W more than enough power, while sport fishers and game fishing boats will generally have a minimum of 1kW with many game boats using 2kW or even 3kW transducers for the best possible performance when looking for canyons off the shelf.
• Transducer Frequency – today most transducers over 600W are dual frequency meaning that the transducer has the ability to look at high and low frequencies at the same time. 50/200 kHz is by far the most common in transducers however in upper end 1kW plus transducers 28/200 and 38/200 kHz is also common.
Basically the differences in frequencies can be explained as follows:
- 200 kHz is the best option in water under 200ft/60m if you need to get an accurate reading while moving at faster speeds. High frequencies give you greater ability to detect very small objects but over a smaller portion of water. High frequencies typically show less noise and fewer undesirable echoes while showing better target definition.
- 50 kHz is the best option for deep water. This is because water absorbs sound waves at a slower rate for low frequencies and the signal can travel further before becoming too weak to use. The beam angle is wider at low frequencies, meaning the outgoing pulse is spread out more and is better suited for viewing a larger area under the boat. However, this also means less target definition, separation and increased susceptibility to noise. Although low frequencies can see deeper, they may not give you a clear picture of the bottom.
Mud, soft sand, and plant life on the bottom absorb and scatter sound waves, resulting in a thicker bottom image. Rock, coral and hard sand reflect the signal easily and produce a thinner bottom display. This is easier to see using the 50 kHz setting, where the bottom returns are wider.
Radar Stand Along Units and Domes and Arrays
Radar is an acronym meaning Radio Detection and Ranging. It is a device which not only measures the time it takes for a pulsed signal to be reflected back from an appropriate object, but also determines its bearing relative to your position. Once the time and bearing are measured, these targets or echoes are calculated and displayed on your radar display. This will give you a bird’s eye view of where other targets are relative to you, even when you cannot see them with your eyes due to low visibility.
What can radar do for me? With radar acting as your eyes, you have the ability to see objects (targets) such as landmasses, weather systems and other vessels to assist you in the navigation of your vessel.
There are many things to consider when buying radar. Here are a few:
• Boat Size – radars are available in various sizes and configurations. The most popular are Radom’s and open array scanners. Radom’s are the most popular configuration due to their compact size, lower power consumption and lower purchase price. Open array scanners are popular with larger vessels because of their increased performance due to the narrower beam angles, higher transmitting power and better target definitions.
• Transmitter Power Output – a higher power output level increases the radar’s ability to receive signals reflecting off objects and show them as targets on your display. Higher-powered radar also has greater capacity to ‘punch through’ fog and precipitation, allowing you to see objects around your vessel.
• Beam Angle – this specification is related to the length of your antenna. The longer the antenna is, the narrower the beam angle. This narrow beam angle increases the radars bearing resolution allowing you to discriminate easily between two objects that are close together. It also shows land mass contours and inlets with much greater resolution.
Can I navigate with radar? Fishing vessels and pleasure boats commonly use radar to help them navigate to their favorite fishing spots. When heading to a particular spot, the forces of wind and current combine to shift the vessel off its intended course. To determine your position and to counter vessel drift, use the VRM (Variable Range Marker) and the EBL (Electronic Bearing Line) to mark range and bearing to fixed targets.
Autopilots
For any passage making boat or yacht, an autopilot is a necessity. The thrill of steering a boat on the open ocean is quickly diminished when one realizes how tiring it is especially if there are many more hours ahead. An autopilot gives you the ability to accurately navigate to a point without having to touch the helm. In many ways an autopilot especially if fitted with a rate gyro and interfaced with a chartplotter can out steer and navigate a straighter course than even the most seasoned skipper (and it doesn’t get hungry or thirsty!).
Autopilots comprise of several main components:
• The Head Unit – this is the controller for the autopilot. Every manufacturer has different styles to suit various applications and tastes. Many can have multiple stations and be wireless giving the skipper the ability to tend to lines and rigging while underway or just sit on the deck and enjoy the surroundings.
• The Course Computer – this is the brains of the autopilot. It basically takes the information from its sensors/GPS chartplotter and tells the drive unit which way to steer the boat.
• The Drive Unit – this creature steers the Rudder, sterndrive or outboard. There are several types or drive units with the most popular being hydraulic drive (for hydraulic steering), rotary drive (for chain steered yachts), linear drive (for mechanical steering), wheel drive (attached to the helm wheel) and tiller drive (attached direct to the tiller).
• The Rudder Angle Indicator – This device tells the course computer what position the rudder is, thus allowing the course computer to calculate how much rudder or counter rudder needs to be applied.
When selecting an autopilot you first need to select your drive unit to suit the steering mechanism of the boat. Secondly, select a course computer/corepack. This is sized to the boats size and weight. The key point here is not to undersize a system for when the seas are rough, you do not want the system struggling and or worse, failing. The final step is to select a head unit to drive the system.
You quickly realize how useful an autopilot is when correctly sized and installed.
Interfacing
Most modern marine electronics now support either NMEA 0183 or NMEA 2000 which are combined electrical and data specifications for communication between marine electronic devices such as fish finders, autopilots, GPS receivers, engine data and many other types of instruments. NMEA communicates via data sentences between devices which support either 0183 or 2000 so that different brands can be used in a system. In most cases this is perfectly fine, however if any of the data (check sums) is different than certain functions may not work between the two devices.
If you want the best reliability in a system between devices, it is often best to stick with the one brand throughout, from both an aesthetic and resale perspective.
COMMUNICATIONS
Marine radios are essential safety equipment for communicating with other boats, marine rescue groups and to receive navigational warnings and weather updates. There are three types of marine radios:
VHF - the VHF radio remains the most versatile communication device for a boat and is often the only communication device most pleasure boats carry. Due in part to its versatility , the VHF is arguably the most valuable piece of safety gear aboard, delivering any call for assistance to dozens or hundreds of nearby listening ears
Fixed Mount or Hand-Held - modern hand-held VHF radios are full featured, extremely convenient, and they have the significant advantage in an emergency of being independent of the boat's electrical system. Where maximum range and/or continuous use are more important, you will want a fixed-mount unit. If your budget allows, having both offers additional advantages, such as two-way communications with an excursion party (but note, transmissions from ashore is prohibited without a coast-station permit).
The VHF radio is NOT a telephone
Boaters often use the VHF much like a telephone to call other boats and shore stations to relay information, to make appointments, or sometimes just to chat. Before you join in, however, you should recognize the differences between VHF radio and telephone communication: Radio conversations are not private. When you talk on the VHF, everyone within range tuned to that channel is listening. A radio conversation ties up the channel you are using. No one else up to a 25 mile radius can use it until you release the transmit button on the microphone.
Use of low power
All fixed-mount VHF radios can transmit at either 25 watts or 1 watt. The maximum power from a handheld is typically 5 watts. With either type, if your radio contact is nearby, set the power setting to low (1 watt) to reduce the distance the signal carries beyond your target. Also watch your language; not only is profanity over the air against the law, it will be particularly offensive to other boaters with children aboard.
HF Radio
HF Radios have a greater communication range if travelling long distances from shore. Queensland HF services cover coastal waters to a minimum of 200 nautical miles seaward from sites located at Cairns and Gladstone. These Stations maintain 24 hour listening watches on 4125 kHz, 6215 kHz and 8291 kHz for distress and safety situations. It is important to restrict radio traffic on these frequencies to distress, safety and urgency calls. The 'Coast Radio' Stations will also broadcast navigation warnings on 8176 kHz.
HF radios are expensive to purchase, they require far more experience to operate than a VHF as you have to tune them in and they also require careful consideration with installation as earth plates, grounding straps, antenna tuners, deck insulators and special antennas will be required. If not installed correctly radio performance can be severely hampered as HF radios are very prone to electrical interference. Cost is install is also far greater than that of VHF.
If you are venturing far off the coast then a HF Radio is a good investment as it offers a far superior range than a VHF radio and it also offers more security than a Satellite phone. You can only call one person on a Satellite phone where as you can reach many people in one call with a HF radio.
Both VHF and HF radios require the operator to obtain a Marine Radio Operators Certificate of Proficiency (MROCP), which covers the operation of both VHF and MF/HF equipment. The Marine Radio Operators VHF Certificate of Proficiency (MROVCP) has a somewhat simpler syllabus, but only covers the operation of VHF equipment. Most coast guard, VMR and certain yacht clubs will run these courses though out the year.
Antennas
Knowledgeable boaters realize that even the most expensive radio will perform poorly with a second rate antenna that may well save you money up front, but may jeopardizes the welfare of those aboard in time of need. That’s why we prefer the quality, performance and reliability of Shakespeare marine antennas.
Shakespeare fiberglass antennas are built with precision, beginning with hand-soldered connections, brass and copper elements, strong mechanical joints and superior electronics. The radiator and electrical elements are then encased in an exclusive Shakespeare fiberglass radome.
Tips on choosing the proper antenna
Since there are many factors that influence the selection of a proper antenna for a specific application, we encourage consultation with a local dealer, whenever possible.
When this is not possible, the following tips should be considered before making a final decision.
• Antenna Length – height is paramount in getting the greatest range, and encourages the selection of an antenna that can be placed as high as possible on the boat.
• Sailboats – as a general rule, sailboats have a 3’-5’ antenna mounted on the masthead. Some racing enthusiasts opt for an 8’ antenna mounted on the stern in the event demasting should occur. Either is acceptable. A decision should be made on personal preference.
• Powerboats – most power boats from 16’ to 25’ in length use a standard 8’ antenna, while bigger vessels have the option of larger antennas with more gain. Caution: be sure to allow enough lay down room for clearing low bridges or other limitations. Whichever choice is made, a sturdy mounting arrangement must be used to avoid damage to both boat and antenna.
• Gain ¬– this is a rating stated in decibels (dB). Generally, the higher the gain, the greater the communicating range. However, keep in mind that the higher the gain, the more compressed the beam width becomes. A narrow beam can cause fading in rolling seas. Small, lightweight boats, which roll excessively in heavy seas, normally do not use a gain rating above 6dB. The more stable the platform of a vessel, the higher the gain that can effectively be used.
• Mounts – be sure to pick the mount style that will best support the antenna on a particular boat. When using a two-piece antenna system greater than 10’ in length, an upper support clamp is necessary. For antennas of 14’ to 18’, the upper clamp should be 3’ to 5’ from the bottom. For antennas of 18’ to 23’, the upper clamp should be 4’ to 8’ from the bottom. Positioning the upper clamp too high or too low can significantly increase the potential for structural failure.
• Cable – RG-58 cable is sufficient for cable runs up to 20’. For runs over 20’, larger and better, low loss RG-8/X, RG-8A/U or RG-213 are preferable. Shakespeare uses Low loss, UV stable RG-8/X throughout its Galaxy antenna line. Today’s enhanced cellular services, which operate in the 1800-1900 MHz range place even more importance on using a high quality coax. That’s why Shakespeare developed its exclusive Lo-Max® cable for dual band cellular antennas. Its low loss characteristics are near those of larger RG-8A/U and RG-213 cables, without the extra bulk and rigidity. For optimum performance from your VHF, HF/SSB and cellular communications systems, the cable should be kept as short as possible. Caution: cable supplied with some antennas may not be cut or altered. Be sure to check the instruction sheet before attempting to shorten the cable.
• Low Angle Radiation – Shakespeare pioneered low angle techniques in marine antennas in the 1960s and built them into many models. Low angle minimizes fading while maximizing range even during excessive boat roll in turbulent seas. A normal angle shortens the range and wastes power.
The greatest tip to keep in mind is that no matter how much you pay for your radio, its performance will be directly proportional to the quality and performance capabilities of the antenna. Don’t compromise ... insist on a genuine Shakespeare Antenna.
As you can see there is so much to take into consideration when planning your electronics and communications and we have not talked about other devices such as AIS, wind instruments, forward looking sonar’s, Deck cameras, thermal imaging cameras ... and the list goes on. I recommend that you start planning what you want to put on your boat but hold off on purchasing until you are ready for installation so that way you get the latest versions and are confident about compatibility and functionality.
