Why You Should Consider a Vessel Monitoring System

Eric ColbyMarine Electronics, Marine Electronics Newsletter

With boats getting more sophisticated, an owner would do well to add some technological help when it comes to keeping track of the health of on-board equipment. That’s why monitoring systems are growing in popularity and working their way into what would previously have been considered smaller boats. Monitoring systems can help track things like battery status, fuel and water levels and can send an alert when the bilge pump starts or smoke or carbon monoxide detectors are triggered. Some also offer geofencing that alerts the owner when the vessel is moved outside a set distance. At the International BoatBuilders…

The Benefits of a Dock Boost Transformer

Eric ColbyMarine Electronics, Marine Electronics Newsletter

Pulling into a transient slip at a new marina can sometimes feel like a game of Russian Roulette. When you plug in to the shore power pedestal, will the connection be clean? Will your boat’s electrical system be blown up by a massive surge or will the power sag and try to drain your system. In a freshwater facility, is there current leaching into the water that could lead to an electric-shock drowning incident? For sail and power cruisers, a dock boost transformer could be a worthwhile investment. ASEA Power Systems in Huntington Beach, Calif., makes Dock Boost Transformers that…

Masthead VHF antennas

Bill MorrisMarine Electronics, Marine Electronics Newsletter

In the age of cell phones, satellite phones and long-distance HAM/SSB radios, your marine VHF radio is still the most basic, foundational, go-to electronic communication device on your vessel. But a good, properly installed VHF is worth nothing unless it is properly grounded and connected to an external antenna, preferably at the masthead. With prices ranging from around $50 to roughly $500, depending on length, mounting system and type of vessel, the span of choices can at first be intimidating. Among most cruising boats ranging from, say, 30 to 45 feet LOA, the size of boat is irrelevant when it…

Marine Stereo Systems

Bill MorrisMarine Electronics, Marine Electronics Newsletter, Newsletter

Cruising on our vessels along the coast or on the high seas is exciting, but sometimes we require a bit of entertainment to fill the hours between conversations with crew and other fellow cruisers in VHF and HF radio conversations. A remote-controlled stereo system with wireless speakers is an easy, affordable way to bring some extra cheer aboard while we count the nautical miles left to our next anchorage. Before you shop for a stereo system, keep in mind some stereos include speakers while others do not. If you already have dependable, waterproof speakers mounted out on deck, then all…

Stay Safe with a Depth Sounder

Bill MorrisMarine Electronics Newsletter

A critically important piece of equipment for all vessels, both coastal and offshore is a depth sounder. On many boats, standing watch today means shifting effortlessly through full-color screens showing GPS mapping, depth sounder/fish finder, anemometer, radar and other features through an NMEA 0183, NMEA 2000 or open source network. However, sailors who depend on paper charts and minimal electronics—VHF radio, handheld GPS and a stand-alone depth sounder—are still making successful ocean passages, blissfully innocent of the compulsion, or ability, to spend a fortune on more elaborate systems. Just to refresh our memories, a traditional depth sounder consists of a…

The Latest Tech in EPIRBs

Bill MorrisMarine Electronics, Marine Electronics Newsletter

What started out decades ago as a military tracking device has become standard equipment on offshore cruising vessels: Emergency Position Indicating Radio Beacons (EPIRBs). Fortunately for today’s coastal and offshore cruisers, numerous manufacturers compete to give us the best EPIRB technology, battery life and ease of use. When we sailors go shopping for marine products, we have the advantage of choice and competitive pricing, and the same goes for EPIRBs. McMurdo, RescueME and ACR Electronics are among the leaders in both technology and competitive pricing. The McMurdo SmartFind G8 Automatic EPIRB is a revolutionary device, the first to combine both…

Streamline your electrical system with a new panel

Bill MorrisMarine Electronics, Marine Electronics Newsletter

by Bill Morris As a vessel and its crew evolve together, new electrical systems replace the old, and often new switches are added on separate mounts in odd places throughout the cabin and pilothouse, creating a confusing and potentially hazardous living space. Installing one or more new electrical panels, including a few extra switches for future equipment add-ons, will alleviate the headache and cluttered appearance of a cabin full of multicolored lights glowing like a Christmas tree. With the multitude of manufacturers and panel styles, both AC and DC, available on the market, you should have no trouble picking out…

Electronic wind indicators

Bill MorrisMarine Electronics Newslettermarine

by Bill Morris Whether you are racing or cruising, knowing your precise wind speed and direction while underway contributes greatly to sailing strategy as you count down the miles remaining to your destination. But before you run to your local chandlery to select a digital or analog wind sensor and display, consider the wide array of options in these systems and find the package best suited to your needs. Some wind indicators are available as stand-alone units while others are included as part of a larger kit, which may include a thru-hull depth finder with transducer and a GPS receiver…

Stay on course with electronic charts

Bill MorrisMarine Electronics Newslettermarine electronics, marine gear, multifunction display, navigation, voyaging

by Bill Morris Staying on course under sail, particularly within 100 miles of any coast, is a lot easier with a modern, GPS-controlled chartplotter. With the latest generation of chartplotters, you can navigate to virtually any point on the world’s oceans while staying on course and out of harm’s way. To start off, there are two types of digital charts: raster and vector. Raster charts are digitalized copies of paper charts, such as those published by NOAA and the British Admiralty. On the other hand, vector charts are purely digital, capable of changing the amount of chart detail depending on…

SSB whip antennas

by Bill Morris If you have chosen to install a single-sideband (SSB) transceiver with an automatic tuner on your vessel, you will also need to install an antenna system capable of transmitting and receiving from 0.5 to 30 MHz, come rain or shine anywhere on the world’s oceans. On sailing vessels less than roughly 50 feet LOA, the common practice is to install a backstay antenna. This requires removing the backstay, cutting out a long piece of the wire and reinstalling it with insulators to ensure transmitted power is kept safely above the heads and hands of crew. Another approach…
