Re: Pros and cons of steel sailboats

One way to reduce weight in a steel boat is to take a serious look at how existing components do a structural job, before duplicating them. Chines and centerelines are huge longitudinal angle irons, structurally. The hull deck joint is a huge longitudinal T section structurally, as are side decks . The centreline tank top is a huge fully welded longitudinal bulkhead, structurally. All of these components are, structurally, the equivalent of fully welded longitudinal bulkheads. The cabin sides are beams on edge , with the top welded to the cabin top , and the bottom fully welded to the decks ,not likely to go anywhere. Yet one often sees totally redundant knees and other reinforcing bits and pieces welded in these areas, displaying a total lack of comprehension of the roles played by these components in the overall structure of a shell.
