For the past 30 years, lead-acid batteries have always been the principal limiting factor in the design of high-capacity DC systems for sailboats. Over the years a number of technologies have been developed that attempt to circumvent this roadblock—NiCad, nickel metal hydride (NiMH), lithium ion (LiI), fuel cells—but none has had sufficient life expectancy at a price affordable enough to be
Edited By Mark CorkeBetter Water-Tank VentJim Hancock sends us this idea from New Zealand, where he and his wife, Eleanor, cruise aboard their Freya 39, Solstice. Solstices freshwater tank vented into the bilge, so when the boat heeled, water from the tank would siphon into the bilge. Jims solution was to buy an inexpensive off-the-shelf dishwasher air gapa device that
The cockpit lockers on my 20-foot trailersailer leak because the lid destroys any seal that is attached to it. Ive resigned myself to needing a waterproof container for anything I store there, but I still have to deal with the water that has leaked in. My solution was to attach a small electric bilgepump (with a hose) to a handle. I used 1/8″ by 1″ aluminum bar stock, which is easy to
In the “Know-How” section of the March issue, Steven J. Henkind wrote about how fuel gauges operate and how you can prevent fuel-gauge errors. Here’s the mathematical formula he discussed in the story. You can also calculate the amount of fuel in a tank mathematically. For a rectangular tank, the calculation is easy: the overall volume of the tank = Length x Width x Height; if the
Most of us sailor types would rather fuss over the rigging and the sails than service that big chunk of metal in the engine room, but it’s also the case that most of us turn to the diesel in times of need, and any engine will have its time of need. Spring commissioning is such a time. It’s also true for the outboard. Here is how to be your engine’s best friend, and it comes with a tip: As you go
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
