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

The Price of Power

by Nigel Calder, Posted June 17, 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 desperate need of

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

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

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.

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

Silence on the hook

Simple electrical upgrade

by Peter Nielsen, Posted August 3, 2009

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

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
