oh cool, now I see whats going on
Very much the organic shape of the former HP's

OK the LW hull,
my concern would be that being a wavepiercing design its going to find itself submerged in much of a sea. For the same reasons we like clearance under a bridgedeck, we need freeboard or the boat will be torpedoing underwater all the time with a sort of stop-go motion.

Just what is acceptable clearance is a much debated subject in multihull design, with new boats (which are large but possibly just as beamy) going to 900mm or so. The trend over the past few decades has been on the increase. Perhaps a point of some conjecture, but I would think freeboard ought follow the same rule.

Consequences necessary to cover are the absolute watertight integrity of the access hatches.

If I may, I would suggest the LW hull, and indeed the WW bows, could go above the crossbeams and not add a whole lot to weight.

I like the cabin arrangements, the whole boat does appear to be minimal in weight contribution yet a visually interesting interior space. The impression or feel of space is increased by the way you have arranged the glazing.
