Ebb: "This is a trial idea in doorskin. What are the pros and cons? The laminated beam would go under the one already there (too massive! lost head room!). But it would open up the longer berth room the skipper requires. The doorskin shows a compass curve, the strongest architectural shape possible, in the only form possible, or am I missing something. The present compression beam with its struts imho is perfectly adequate. The arch is strangely more pleasing to me than what's there."
