Smart Regulators and Happy Engines

by Sail Staff, Posted August 16, 2011
A smart regulator can boost your alternator’s charging performance, which means you don’t need to run your engine as long to keep your batteries happy. Sterling Marine Power’s ProRegD digital alternator regulator can be tailored to your battery type—flooded, gel, or AGM—to ensure the most efficient four-step charging schedule.

AIS for Sailors

by Peter Nielsen, Posted May 7, 2009
Any sailor who has made extended passages along coastlines or across oceans has had at least a few close callswith big ships whose course and intentions can be difficult to discern until the last minute. The introduction of AIS (Automatic Identification System) has taken a lot of the guesswork (not to mention terror) out of these close-quarters situations. For just a
Of all the things that scare boat owners the most, sinking is probably at the top of the list. But fire is no less of a threat. Indeed, a fire, even if you manage to put it out, can easily lead to a sinking.

Wi-Fi for Sailors

by David W. Shaw, Posted May 8, 2009
The term Wi-Fi gets bandied about plenty these days. After all, you probably use it to obtain high-speed Internet access at work, in airports and hotels, or at home, and you’ve probably used it on your boat, likely with varying degrees of success. Built-in Wi-Fi hardware in laptops, or PC Wi-Fi-card adapters (802.11 cards), such as those from Linksys, work fine if you’re close

Hybrid Power Keeps Going

by Joseph Huberman, Posted March 20, 2006
The diesel-electric hybrid as an auxiliary power source for sailboats has moved from the laboratory into the water. Though still in early development, it has advantages including fuel efficiency, ease of handling, responsive motor control, low sound levels, immediate-use capability, and, on some systems, power regeneration.I have a Solomon Technologies motor and a Glacier

GPS system questions

by Peter Nielsen, Posted May 20, 2009
The Government Accountability Office’s report last week on the parlous state of the Global Positioning Satellite system should set alarm bells ringing. When a body like the GAO warns that the GPS system is in crisis, all of us – not just sailors – need to take notice. GPS technology is so omnipresent in modern life that few areas of transportation remain unaffected by it.The GAO report
