Water power

by Nigel Calder, Posted August 17, 2009
My last two columns discussed the high cost of generating electricity with a diesel engine and the relatively short payback period for solar panels on liveaboard cruising boats. The problem with solar is that it requires a lot of surface area to produce significant amounts of power. This is relatively easy to find on catamarans, but not so on monohulls.Coincidentally, I received an email

Fresh air below

by Warwick M. Tompkins, Posted August 4, 2009
Despite all the progress in sailing gear and equipment certain aspects of life at sea never change. Keeping water out, maintaining good boatspeed, preserving and conserving food stores, and carrying adequate spares for the inevitable failures that occur are all perennial priorities. Plus one more thing; having a good supply of fresh air below.Someone once observed that
Our 1973 Norlin 34 project boat had been used mainly for club racing in its latter years, and it showed. Among its many outdated systems was the battery-management setup. It was no worse than what I suspect can be found on many other boats of that vintage, but it would not suffice for extended cruising.The two Group 27 90AH deep-cycle lead-acid batteries, one for house

Silence on the hook

by Nigel Calder, Posted August 3, 2009
As part of my hybrid-propulsion research I have been looking carefully at large-capacity Litihum-Ion batteries as a possible energy source on modern cruising sailboats. Lithium-ion batteries are common in cell phones and laptops, but they are rarely used in higher capacity applications. This may rapidly change, because the hybrid automotive and electric vehicle markets are in

Easy controls

by Peter Nielsen, Posted July 22, 2009
The twin-lever engine control on our Norlin 34, Ostara, had been annoying me for as long as we’d had the boat. The detent was so worn that it was sometimes not possible to tell if you were in neutral or reverse gear. More than once I had been alerted by yells from the neighboring boats as Ostara sidled crablike around her mooring, pulled by the prop walk of

Fix-it kit

by Sail Staff, Posted June 22, 2009
Nothing will ruin your cruise faster than a damaged or torn sail. With the BoatWorks sail-repair kit on board, you’ll be able to make emergency repairs and keep on sailing. Ours cost less than $100 to assemble but could save us hundreds in repair bills.A. Curved and straight needles of different diameters.B. Stainless-steel scissors for cutting thread and sailcloth.C.

Keel improvements

by Peter Nielsen, Posted June 22, 2009
Jabberwock, the BoatWorks project O’Day 25, was looking very scruffy around the underparts. The boat had been standing for so long that most of the paint had just fallen off the bottom, and the keel was looking particularly seedy. There was no way we could launch the boat with the keel in such bad condition. It was time for a makeover. A proper keel job done by a boatyard will cost

Keep it simple

by Sail Staff, Posted June 17, 2009
The decks on Horizon, our Hans Christian 38, are 20 years old and have seen the full spectrum of weather conditions—cold and rain for weeks on end in Alaska and constant sun and heat in the tropics. No matter where we are, our maintenance strategy is the same: keep it simple and keep it silver. As with anything boat-related, proper maintenance now is always much easier than an extensive
