You are certainly getting proficient at sketch up. The overall boat
looks quite well proportioned

The crossbeams seem much too low. They will be plowing into waves
down there. I know it means further for the rudders to go to reach the
water, but the extra leverage is a price we have to pay to have the
rudders on the crossbeams. I'd put the crossbeams at least with their
bottoms level with the bottom of the lw lockers, then bring the
lockers even further forward and attach the rudders there. I would
like a minimum of 750mm clearance at the lw hull end. The bridge deck
can be lower as it is in the sheltered area. I like your galley
layout. I am assuming you will be able to weather proof with clears
and mosquito proof.
I am also assuming that the hard edges are part of the limitation of
easy sketch up and the edges would be radiused at least 50mm to reduce
drag and damage to people.
The lw hull could be made to work if the edges around the centre area
were boxed in to make a nice stiff structure, but there are a lot of
holes. Does the centre deck really have to be that low. Check out
the Australian Puddle duck racer for quite a nice explanation of the
effect of boxing in.
I would much rather have water leak into the ww hull than a battery.
I'd store water down low in the ww hull and batteries in a separate
compartment of their own. You'd also get a greater density using water
as there isn't so much air between things. You can easily go through
half a ton of water on a trip. You don't really want that much weight
slopping around unsupported. In the hulls, much of the weight is
supported by the water pressure outside the boat. You could easily get
that much volume under the sole , but make sure you have separate
compartments and baffles in the compartments. Pantry stuff can go into
some of those cupboards, though if you are going offshore in anything
at all nasty, strap them in.
I am thinking of having the potential of some extra storage of water
in the lw hull if I think I may be going on a bit of a dry trip.
Solar panels on the roof with a watermaker would reduce the need to
carry as much water, and you could do some extra charging under kite
when trying to slow down the boat sufficiently to fly the kite.
