Actually, if she sits on her waterline, I don't see where there would be much bridgedeck clearance, with lots of wetted surface. I'd think she would pound/slam in some chop and be pretty slow. Relatively narrow hulls, lots of weight, solid foredeck -- I'd think she would hobby-horse quite a bit, but maybe the bowbulbs help to minimize that. But, I'm no yacht designer
If you're looking to keep the budget
under 180K Euros, there are actually some pretty interesting cats & tris around for that price
and under that would be a far better sail. Better sailing actually means far more comfort.
There are several good books
out there on multihull
design, though. Chris White's, Charles Kanter's, Gregor Tarjan just came out with a new one (though I haven't seen it). Might want to check out one or more of them.
