Marine Electronics

Ever wish you had X-ray vision and could see under the water—without going for a swim—to check the anchor or prop, or to inspect your hull? Well, Aquabotix Technology Corp. developed a product with the goal of giving you that power—at least a limited version of it.

Remote microphones for fixed VHF radios are great tools for both coastal and bluewater sailors, but they can be essential for shorthanded crews. Practical Sailor rounded up and tested six units, each designed to work with two or more compatible, fixed-mount marine VHF radios. The test field included the latest wired and wireless remote mics from Icom, Standard Horizon, Raymarine, and Garmin. To select the best VHF remote mic, testers considered performance, audio systems quality, user-friendliness, features, durability, and ruggedness.

When it comes to onboard stereos, most small and mid-size boat owners want a simple, affordable sound system with a decent audio that can withstand life in the marine environment. To find out what the options are for the cruisers who just want a basic stereo system, Practical Sailor took a look at marine stereo-speaker kits priced under $200. Testers evaluated four budget-friendly audio packages: two kits from Dual Electronics, the AMCP400W and the MXCP43; the CDX-M20 from Sony Corp.; and the ME-52 amplifier from Poly-Planar.

When shopping for a new stereo system, be sure to evaluate the following closely to be sure the package meets your needs.

Sometime around 1:30 a.m. April 28, while participating in the Newport-to-Ensenada Race, the Hunter 437 Aegean sailed directly onto the rocky cliffs of North Coronado Island off Mexico’s Pacific coast. Fellow racers came upon pieces of the boat and reported their findings to the U.S. Coast Guard. The bodies of three crew were discovered with the wreckage. The body of the captain was recovered 16 days later. Contrary to news reports stating there “was no sign of distress” aboard Aegean, an SOS distress call went out from one of the crew—but by the time the Coast Guard learned of it, it was too late. Someone sent a distress alert form the captain’s personal SPOT Connect, a portable satellite emergency notification device (SEND) that delivers SOS messages and vital information—ship’s position and user identity—via Globalstar satellites to a third-party emergency call center.

As a follow-up to our June 2012 report on mid-priced VHF radios, Practical Sailor tested seven fixed DSC-capable VHFs priced above $300. Because most high-end VHF marine radios offer excellent performance, testers looked especially close at extra features, price, and warranties. We evaluated one radio from Standard Horizon, the Matrix AIS+ GX2150; three from Icom, the IC-M424, IC-M504A, and the IC-M604A; two from Garmin, the VHF 200 and VHF 300; and one from Raymarine, the Ray 218. In addition to the bonus features like AIS, position tracking, and hailer/foghorn capability, testers looked at NMEA network compatibility, screen display, audio output and quality, transmit power and power stability, power draw, and frequency stability.

A Rundown on Common VHF Features and Functions

Practical Sailor evaluated the Garmin 740s chartplotter-sounder and other similar sized plotter-sounders in the November 2011 issue. For this follow-up report, we took a close look at the new Raymarine e7D. The Garmin 740s and the Ray e7D are similar in size, and both have a baseline plotter with sounder functionality, but the e7D has many new capabilities that include WiFi and Bluetooth interfaces witth mobile computing devices such as iPads and iPhones. The e7D is also capable of being fully networked with the other members of the new Raymarine chartplotter family and the C- and E-series widescreen units, while the Garmin 740s was designed as a standalone, multi-function display system.

Raymarine has re-defined onboard interface with WiFi and Bluetooth capabilities in its new MFDs. Using an iPad or iPhone (Version 4 or newer), a Kindle Fire Tablet, or any Android Smartphone or Tablet, users can stream the e7D display to these devices using the RayView free app downloadable from iTunes, Amazon, or the Google Play Android store. This allows you to use these devices as a second display.
