Apps and Computer Programs

Looking to add GPS functions to WiFi Apple devices or increase the GPS accuracy of a Bluetooth device? U.S. company Bad Elf created the GPS Pro, an external Bluetooth wireless GPS receiver and data logger, to simultaneously share GPS data with Bluetooth-capable i-devices, including the iPhone, iPod Touch, and iPad. It also can serve as a standalone data logger that allows you to record up to 100 hours of trip location data.

Nobeltec, a marine-navigation software developer based in the U.S., recently released a new chartplotting app for the iPad: Nobeltec TZ. We took it for a weeklong test cruise and found it to be a good basic nav program with some significant strengths, and some notable shortcomings.

As a followup to our April 2012 report on useful iPad apps for sailors, we recently sea-trialed the new Weather4D app, comparing it to the older WeatherTrack app. Both enable users to view GRIB weather files, but which one does it the best and which one offers the best value?

There are still not as many marine navigation programs for Mac computers as for there are for PCs, but their quality often matches that of PC software, and their cost tends to be lower. The Mac software programs we tested were MacEnc, GPSNavX, Polar View, and OpenCPN. Testers have used MacEnc and GPSNavX extensively while cruising, and we evaluated OpenCPN during two three-month cruises and Polar View for a little over a month during another cruise. Prices range from $180 for MacEnc, to free for OpenCPN, an open-source, non-commercial software created by volunteers.

A few issues ago, you had a short article on deck hardware (blocks, traveler, cars, etc.) that included Garhauer, and you mentioned that the manufacturer offered individual parts and complete systems that allow conversion from on deck to cockpit adjustment of the car position. We recently installed the EZ adjustable genoa car system from Garhauer and are very pleased with the results. This equipment fits on existing traveler tracks, is easy to install, and performs as advertised.

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.

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!

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.

Before we plunge headfirst (again) into the world of multiplexers with this test report, heres a quick review of what exactly were talking about. If you have older instruments or a GPS networked to send information to other devices (a multi-function display, laptop, etc.), the information is likely in NMEA 0183 format and is sent in sentences in a set order. For example, the NMEA sentence $GPAAM,A,A,0.10,N,WPTNME*32 is an arrival alarm sentence sent by a GPS to various networked devices upon arrival at a waypoint.

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.
