As a longtime catamaran dealer, I'm skeptical about ALL manufacturer's displacement ratings. Why? Because it's so common to hoist a cat with a crane that has a highly accurate weight gauge, and discover -- surprise, surprise -- that the boat's actual weight is considerably more than that boat's brochure specifies. And when I say "considerably," I can think of one specific model that weighs almost six tons MORE than the brochure says. I pointedly asked the builder why this was so? He told me outright -- the competition does it, and my sales would be much more adversely affected by my not doing the same, as compared to printing the actual weight for my model while also trying to "educate" would-be buyers that the competition is "fudging" with its numbers. Having said that, 41,000 seems pretty substantial. I was in New Zealand when a NZ-designed-and-built 47' power cat was being hauled. The fully accurate scale on the hoist showed just over 28,000 pounds. Of course, different engines and tankage can affect such readings. And I imagine that contruction styles (i.e., solid glass layup vs. cored construction), can make a big difference, too. But again, short of weighing a variety of cats with the same scale, I'd say that the figures given in brochures are, at least some times, more affected by wishful thinking (or competitors' previous "tall tales") than true displacement figures.
