Communications: Improving technology has made satcom ever better at squeezing more data into a smaller package. The result is more attractive capabilities for data usage via satcom. The Iridium satellite system is joining GMDSS and satcom is a growing field, and while HF SSB is still used by many voyagers, its importance as a communications mainstay is receding. The present and possible future of marine communications will be our focus.

Weather
Year in and year out, the number one subject for most voyagers is weather — getting valuable data and applying it to your local situation to take advantage of good wind and avoid storms. We’ll look at what new options are available in products and services for voyagers to handle this all-important task.

A special section on Communications - how to stay connected while voyaging. Also, read about voyaging in a responsible manner culturally and ecologically. Plus, NOAA updates their global weather modeling.

A special Section on Marine Electronics, as well as a near disaster while voyaging in the Pacific.

In the special section for this issue we focus on sun, wind and water electrical power. We have circumnavigator and alternative energy expert Bill Morris looking at configurations of solar, wind and water power for best performance on the modern cruising yacht. Morris explains how these inputs vary based on boat size, ocean sailing versus coastal cruising, and crew needs. In the power voyaging column, expert Jeff Merrill explains that for many of the issues that crop up on a trawler, often the best solution is: RTFM (Read the {Factory} Manual). He discusses how to assemble and organize manuals for easy reference. In the ocean voyaging story, circumnavigator Ellen Leonard describes the magic of making landfall for the first time and how landfall remains special for the ocean sailor every time land appears on the horizon after a passage. In other stories, we get a report from a voyager who has a 3D printer on his boat and uses it to make custom replacement parts and a voyager describes equipment he had aboard and how it performed on an offshore trip that involved heavy weather. Plus, the nav problem and more.

The electronic-based safety gear sector has
been growing, and now there are devices and
apps that handle a wide variety of safety situations
offshore. But these technological advances
haven’t changed the basics of safety aboard a
voyaging boat, which revolve around paying attention,
knowledge and training. We’ll examine
how traditional safety approaches are incorporating
new technology.

In this issue we have a special section on batteries: Storing electrical power is a major issue for voyaging boats. From installing a replacement set of batteries to a survey of active voyagers about the battery setups -  fascinating talks with liveaboards.

Weather: Given that the consequences of getting caught in a major storm can be unpleasant or worse, the number-one issue for most voyagers is getting reliable, useful weather data both in port and at sea. We’ll do a review of both the sources and the uses of weather info so you can make better decisions about your offshore passages.

Watermakers - The first generation of these systems required
considerable manual input to operate. Now,
watermakers are more sophisticated and
require far less operator attention. The biggest
considerations for the voyager now are capacity
and installation questions. We’ll examine these
aspects of watermakers and more.

In the first story we'll compare the modernized version of the voyaging meteorologist's primary tool: the barometer and recording barograph. Our second story reviews the major weather routing service providers with a roundup of the products they provide. Our third story takes a speculative look at how some observers are suggesting that the amount of bad weather is increasing in areas like the Southern Ocean and singlehanded worldwide races may be getting too dangerous. In our Power Voyaging column we look at voyaging papers, the necessary paperwork you'll need when power voyaging in foreign waters. In our Ocean Voyaging section we have a story from way back in 1975: Two Navy pilots with very little sailing experience  sail across the Gulf of Mexico in a stripped-down Ericson 25. Not surprisingly, they encounter a few surprises. An endearing story about just getting out there and doing it and being lucky! In a story on the voyaging life, a live aboard voyager looks at the value of having some language skills other than just English when going voyaging to distant ports of call. And in Celestial Navigation series we have part seven in which we look at using the H.O 249 sight reduction tables and plotting a line of position. Plus, the Nav problem and much more.

A second piece reviews anchoring technique. How to employ various configurations of lines and anchors to keep your boat securely in port. In our power voyaging section we examine propeller removal. A power voyaging boat needs propellers in good shape for maximum efficiency and that means should a prop be damaged or otherwise need replacement, the prop needs to be removed from the prop shaft. Our ocean voyaging story tells of circumnavigating Vanua Levu. The southern and eastern coasts of the Fijian island of Vanua Leu are frequently visited by voyaging boats. The western and northern coasts of the large island are, however, less visited. A pair of liveaboard voyagers make the trip around the island and meet many friendly villagers who welcome to their vibrant little communities. IN a story on electronic charts a voyager looks at recent yachts groundings and the subject of chart accuracy at various zoom levels. The advent of electronic navigation has revolutionized the boating industry by providing a means for sailors with minimal navigational experience to access the planet using GPS and electronic charts. But there are still issues with charts that require attention for safe navigation. In our voyaging tips section we look at voyaging gadgets. A sample of really useful voyaging gear from handheld depth sounders to laser rangefinders to headlamps and label makers. Having gear like this on hand will help make voyaging easier. We also have a story on ways voyagers can reduce plastic. A voyager looks at ways the community of voyagers can help remote island people to collect and  recycle plastic items like water bottles.
