DeLorme inReach vs. Iridium Extreme

There are numerous portable marine electronics that can keep you connected while you get away from it all. But which device offers the most features-tracking, two-way communication, location sharing, etc.-at the best price? And which one can be counted on in an emergency? We began our look at these personal electronics with the January 2013 review of BriarTeks Cerberus Cerberlink and the SPOT Connect. This month, we evaluate the DeLorme inReach, another pocket-sized, satellite communication option for the cruising sailor, as well as the Iridium Extreme 9575 sat phone, which is capable of providing worldwide voice communication.

GoFree: Simrad Nav Goes Mobile

Being natural-born skeptics, Practical Sailor testers are always pleasantly surprised when we test gear that meets-or almost meets-the hype from its makers and marketers. And that was just the case with Navicos GoFree WiFi wireless networking device for Simrad products. We recently field tested it, and found that aside from a few niggles, the GoFree lives up to makers claims, is easy to install, and works well-straight out of the box!

Touchscreen plotter-sounder test: Simrad NSS7 vs. Raymarine e7D

Practical Sailor recently had the opportunity to take a long-term look at the Simrad NSS7 multi-function display from Navico, and we compared it to a similar unit from Raymarine, the e7D. The test focused on the same elements as our past reviews of the Garmin 740s and Ray e7D chartplotter-sounders: installation, screen visibility, environmental tests, and plotter and sounder functions.

Useful and Fun Nautical Apps for iPad

In the February and March 2012 issues, we looked at navigation software that allows sailors to use the Apple iPad as a functional chartplotting device. With more than 140,000 apps available, there are hundreds more apps suitable for onboard use. Testers tried out more than 400 weather apps, knot-tying apps, several just-for-fun apps—like Trip Lingo Pirate Edition—and apps for document storage. This report covers more than two dozen of our most used and favorite sailing-related iPad apps.

PS Sea-trials the iPad and Nav Apps

With many of the 38-million-sold iPads winding up on board boats, it’s no wonder there are hundreds of iPad apps that are well suited for the sailing life. This begins Practical Sailor’s three-part series on those apps. Part 1 of the series reports on PS’s field tests of multiple navigation apps—using raster and vector charts—to see how well they perform and how they compare to traditional navigation software. They review looks at the top performers: iNavX, iPad Navionics, and Charts & Tides.

PS Tests Small-screen Plotter-sounders

Practical Sailor tested four small-screen chartplotter-sounder combo units priced from $700 to $1,500: Raymarine A70D, Garmin 740S, Lowrance Elite-5, and the Humminbird 798si. While there was a disparity in what features the units offer, the plotter-sounders were similar in terms of the GPS-based functions. Testers looked at ease of installation, ease of use, screen visibility, resistance to fogging, and water/spray resistance. They also compared features including price, man-overboard functions, waypoint and route storage, available charts, chart interface, and user interface. This article focuses on the electronics' chartplotter capabilities. The December issue will include the report on the devices' sounder functions.

Plotter-sounders Undergo a Battery of Tests

Fogging screens, water intrusion, poor visibility in bright sunlight, and slow redraw rates are the most common complaints we get regarding plotter-sounders. Better construction, new screen technology, and faster processors in our current crop of units seems to have addressed these issues. None of our products experienced serious problems during our environmental testing. Our tests focused on four key elements:

Local Loft Versus Web-based Service

Not every sailor has a selection of local sailmakers to choose from. He or she must instead rely on Internet research and phone conversations to find the best sail for the best price. As most of the world’s sail production takes place in a handful of high-volume production lofts abroad (China, Sri Lanka, and Africa), U.S. sailmakers have taken on the role of sail designers—rather than sailmakers.

Route-planning Software Review

Practical Sailor editors evaluated Digital Waves Visual Passage Planner software, which is based on the U.S. Pilot Charts and lets users plan a voyage based on historical weather patterns. Testers used the software to recreate the 1888 historical passage by Joseph Conrad. Conrads passage from Bangkok to Singapore, aboard the iron barque Otago, took an excruciating 21 days. By plugging in waypoints, location and time of year, testers were able to see wind, current, sea state, water temperature, and air temperature along Conrads route. Visual Passage Planner showed the average wind speed and direction, as well as the number of days of calm, for the area and time of year. The software is an interesting tool for passage planning, but because it uses historical rather than real-time data, it shouldnt be compared to true weather-routing software like the weather-routing module from MaxSea, which uses a boats polar data to evaluate real-time routing.

Winterizing Your Boat’s Water System

Much of your winterizing success will depend on the initial condition of your existing water system. If it is nearly sterile (effectively chlorinated water), there may be too few bacteria and fungus present for infection to start. However, if you use less than 20 percent alcohol or glycol (after dilution with water left in the system) you are at risk of biological growth; the lower the concentration the greater the risk. This is the reason why vodka and other alcohol-based winterizing fluids should be avoided. In our testing these solutions acted like an invitation to a microbial feast.
