From sea anchors, drogues, and trysails to forereaching and heaving to, tactics and gear for surviving a storm at sea vary greatly. During a high-latitude circumnavigation, Evans Starzinger and Beth Leonard, aboard their 47-foot Van de Stadt sloop, had several opportunities to test heavy-weather sailing tactics. The couples main storm gear was a Galerider sea drogue, made by sailmakers Hathaway, Reiser and Raymond, is a webbing bowl with a wire hoop. Deploying the drogue involved a bridle of strong nylon lines connected to the Galerider rode via an oversized galvanized swivel. Starzinger and Leonard used the Galerider when running before the wind in gale-force conditions. The drogue helped slow the boat, kept it from surfing down the face of a wave, and provided directional stability, which allowed their autopilot to maintain control. Drogues and other storm-survival gear and tactics are particularly necessary for short-handed crews and boats that tend to surf in heavy weather. Other storm gear for sailboats that Practical Sailor looked at included the Jordan Series drogue and the Seabrake drogue.

Internet access onboard is increasingly popular but achieving a reliable wireless connection can be difficult in a marina or on the water. A laptop with a built-in Wi-Fi system is a common starting point, but marinas can be a difficult place for low-power, high-frequency radio signals. Practical Sailor tested 5MileWi-Fi, a system that utilizes an external antenna to extend the Wi-Fi range beyond that of normal Wifi devices.

In the December 2007 Practical Sailor Advisor, you requested feedback on Ultimate Sole, a product for coating cabin soles. Two years ago, I added a -inch teak-holly veneer plywood covering to my sole and used Ultimate Sole as the finish. I first put on a sealer and then two coats of Ultimate Sole. It went on very easily and performed better than I expected. It is a hard, glossy finish that truly does offer nonskid properties. You look at the finish and think you will slide all over the place, but you don't! It is a wonderful product, and I wouldnt use anything else.

On a recent boat delivery from Michigan to Florida, I had the opportunity to try out some new computer-based planning software from EarthNC. EarthNC uses Google Earth images to present marine chart data by overlaying the charts on Google Earth satellite images. For $50, EarthNC provided 757 vector-format charts (raster format charts and other packages are also available) for the continental U.S., Alaska, Hawaii, and parts of the Caribbean. These charts can be used online or offline. When combined with a USB-connected GPS-and the ooPs (www.goopstechnologies.com) GPS software for Google Earth-EarthNC provides a real-time, moving map experience similar to modern chartplotters. EarthNC also has automatically updating weather maps with data supplied by NOAA.

Garmin’s new scroll-wheel Colorado 400c and touchscreen Oregon 400c offer some unique features, but their multi-sport focus falls short in satisfying all of a mariner’s needs. Although both new units are high-quality handhelds, testers preferred an older-generation GPS, the Garmin GPSMap 76CSx, which was the Practical Sailor Best Choice in a previous test. Practical Sailor tests compared the units’ features, performance, ergonomics, and price, along with how well they meet sailors’ needs.

Practical Sailor’s annual wrap-up of the year’s best sailing equipment looks at our favorite top-rated products from November 2007 to November 2008, including the Facnor furler for light-air sails, Scad Solo external holding-tank sensor, Pelican Recoil LED flashlight, and Adventure Medical’s first-aid kit for coastal cruisers. In the boat maintenance category, Interlux’s Micron 66 bottom paint and Spray Nine’s waterline stain remover garnered Editors’ Choice picks. Foulie sets (jacket and bibs) by Gill and Helly Hansen were tapped as Practical Sailor Editor’s Choice in apparel, and a host of marine electronics made the list, including the Icom CommandMic III remote mic and Garmin GPSMap 545s 5-inch chartplotter sounder. Jeppesen was recognized for its top-notch electronic chart updating services. Other top gear picks were the Acco proof coil mooring chain and the Achilles HB315-LX fixed-transom inflatable dinghy.

A decade ago, Practical Sailor editors began scouring boat shows for the perfect emergency tiller and an ideal stowage system for it. Little more than a simple lever arm that attaches to the head of the rudder stock, the emergency tiller is the device a sailor relies on in the event a steering cable parts or theres some other steering system failure. Our seemingly simple search turned out to be a nearly fruitless enterprise. Boat after boat fell far short of delivering even an average emergency tiller. Heres a look at our favorites and favorite offenders as well as our criteria for a good emergency tiller and where to keep it.

Automatic Information System (AIS) devices have been required on large commercial ships since 2002. Their popularity is growing in the U.S. recreational sailboat market, thanks to the Federal Communications Commissions (FCC) recent approval of AIS Class B transponders. Some devices allow users to send and receive information about a ship-location, size, speed, call sign, and MMMI number. Others, like the Raymarine AIS 250, only receive AIS broadcasts from other AIS-equipped ships. The Raymarine AIS250 receives AIS Class A and AIS Class B broadcasts. Practical Sailor found that the device performed well, and was user-friendly and easyto install. But, for a receive-only unit, its pricey: $980, or about three times as much as similar devices on the market. If you already have a Raymarine network and prefer to see but not be seen, then the AIS250 is worth considering.

Ive created a 24-volt system by connecting two 200-amp-hour 12-volt batteries in series to drive an electric outboard as auxiliary power for our 25-foot sailboat. The 24-volt bank will be charged using a 24-volt charger on shore power and by a 24-volt series of solar panels when mooring. I would like to eliminate the 12-volt batteries. I bought a 24- to 12-volt converter to stand in place of the 12-volt batteries, but I learned that the converter is not compatible with driving any kind of motor due to the back-voltage created by the collapsing field when the motor stops. I have a freshwater pump and a motorized outboard-motor bracket, so this particular converter is out of the question. Do you have any suggestions? Must I maintain a 12-volt battery for all the 12-volt equipment or is there a step-down technique?

The test field includes devices with 5-inch display screens that provide chartplotting capabilities and information and show detailed bottom contours on a single display screen. These combination fishfinder-chartplotters are fitted with high-powered sounders. Practical Sailor tested units for day and night visibility. Each plotter was tested with live GPS fix information. Chartplotter user-interface was tested by examining actions such as creating waypoints, building routes, and changing map ranges. Units tested were the GarminGPSMAP 545s, which uses Garmin’s Bluechart g2; the Lowrance LMS-525C DF (a Navico brand), which has an NMEA 2000 GPS sensor, uses Navionics cartography, and is capable of interfacing with a Lowrance radar; the Raymarine A60/DSM25 combo; the SI-TEX Colormax SE; and the Standard Horizon CP180.
