I've got a 56' Performance Marine (DMR)
It's a low house head boat, so it's walk-around deck and the stability is for 63 pax in partially protected waters/ 43 in exposed using the new weight (185 I think.) It's not exactly a lobster boat, but Royal Lowell supposedly designed that hull. There is a Carolina boat not far from here that is about the same length as mine but has sort of a hybrid design, w/ a traditional foredeck and cockpit, but a narrower cabin w/ bench seating built into the sides, and a nice shad overhang from flybridge. I don't know why you couldn't do that w/ a lobster boat, especially a beamy one. No teliing what sort of stability letter you could get w/ one of today's wider hulls. My boat is not very beamy.
