Boatworks Most Commented

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

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
