Handheld Electronics

Although the ease and convenience of electronic chartplotters has ensured their place aboard most every vessel these days, the punch-and-go navigation that makes them so popular has also spawned a generation of slack-jawed zombies when it comes to even the most rudimentary of navigational skills. Prudent mariners continue to carry paper charts, both as backup to chartplotters (and their “one diode away from disaster” nature) and to have the big picture view that a plotter just can’t match.

Practical Sailor contributor and bluewater cruiser Joe Minick details the benefits of an onboard Wi-Fi computer network on a cruising boat, and explains the easy DIY setup that connects multiple electronics to the Internet via a client router. Beyond the usual benefits, one that is particularly useful to sailors is that an onboard network allows networked devices to share GPS, NMEA instrument information and other navigation data using software like GPSGate from Franson Technology and Handheld for Mariners. Minick used the Engenius EOC2610 from Keenan Systems and the D-Link DWL G700AP in his setup, which has served his crew well as they cruise the Med. The ethernet-based system is similar to the the Bullit2 systems PS tested from Bitstorm and Wave Wi-Fi.

Although the Icom GM1600 marine VHF handheld radio is not meant for use as a recreational marine VHF, Practical Sailor was interested in determining whether the unit’s survival-oriented design might make it a good choice for inclusion in a life raft or ditch bag. We were also interested in comparing its specs to another marine electronics product, the Standard Horizon HX850S VHF handheld, one of the top picks from our most recent series of tests (April 2009, July 2009, October 2009, December 2009).

Every November, Practical Sailor editors celebrate the impending holiday season by reviewing gift ideas for the sailors on your list-or to add to your wishlist. This years wrap-up covers a range of interests and includes something to fit every budget. Looking for a new gizmo for the gadget junkie? Check out solar-powered, water-resistant Eton Soulra sound system, which can play most MP3 players and iPods, iTouch and iPhones while charging them. Or take a look at the SolarTech SolarPulse, a solar-powered device that charges and maintains a ship's batteries. The featured galley goodies from Galleyware and JetBoil will make practical gifts for those galley goddesses, and the Sailor's Solutions wireless remote switch for 12-volt devices is a good stocking-stuffer for creative boat owners and those looking for convenience.

Ordinarily Practical Sailor is loathe to apply a $100 battery-operated solution to a problem easily solved with a chunk of lead and some 3/8-inch line. However, portable depth sounders take the leadline to the next level. Resembling small flashlights, these handheld sounders are designed to be portable, easy to use, and reliable. They are good tools for probing creeks and narrow passes in a dinghy, and also can serve as backups to a primary sounder. This series of tests took a look at the Hawkeye 22PX from Norcross Marine and the Speedtech Depthmate SM-5A. On-the-water testing comprised a series of six tests in specific locations. Each unit was tested in murky shallow waters with a soft mud bottom; moderately clear waters with grass bottom; and clear waters with sand bottom. Testers also evaluated whether the sounders could read through hull materials, their durability and waterproofness, and whether their digital displays could be read in bright sunlight and at night.

Joe and Lee Minick added an Automatic Identification System (AIS) receiver to the nav station of their Mason 43, Southern Cross, and have used it for several years in some of the most heavily traveled waters of the world. Required on large commercial vessels, AIS devices add a whole new dimension of collision avoidance, transmitting dynamic information about a vessels speed, course and position plus static information including a vessels name, call sign and Mobile Marine Service Identity (MMSI). With a Class A AIS and a more recent Class B AIS system for small craft, AIS changes the landscape in marine navigation. The Minicks report in Practical Sailor proves how useful AIS can be for cruisers and other small boaters.

While it sometimes seems marine electronics marketers are piling on unnecessary features just because they can, anyone who has watched their $300 cell phone disappear over the rail or has missed a call from the boss while they were playing hooky on the water can appreciate Cobras newest handheld marine VHF. The MR HH475 FLT BT is a full-feature, floating handheld VHF that can also link up to any Bluetooth-enabled cell phone. The radio uses a tiny wireless Bluetooth transceiver (the same technology used to link cell phones to wireless ear buds) to synchronize with your cell phone. When you go for a sail, you can put your cell phone belowdecks and use your VHF to monitor and receive any incoming phone calls.

The June 2010 issue featured letters on subjects such as: spiders, addition of color to handheld electronics, DIY boatyard recommendation and propane fridges.

After testing navigation applications for Windows-based smartphones and PDAs, Practical Sailor focuses on three apps available for the iPhone. iNavx, Memory-Map, and Navionics can each be downloaded for a reasonable price and used as backup to primary navigational aids such as a chartplotter or handheld GPS. Cellphone-based programs are not recommended as a standalone approach to navigation, but the iPhone apps are a great way to investigate, plan routes, and set and send waypoints at a very low cost for cartography.

We know the drill now. If we feature a Mac product, we have to appease the PC crowd, and vice versa. Otherwise, the earth spins off its axis and our inbox starts smoking. So while the iPhone crowd gets their fill with our review of navigation apps (page 24), heres a morsel for readers using Windows Mobile devices. After testing several navigation programs for Windows Mobile handhelds in December 2009, we had the opportunity to evaluate Memory-Maps Weather Radar for Windows Mobile cellphones.
