What you see is the insert (or plant as the infusers call it) for the windows. On the inside of this is a 50mm wide flange on which the windows are bedded. So the size of unsupported window is considerably less than the insert. There are also pillars so the window is split into three seperate pieces. Assuming the 6mm acrylic windows are strong enough, they will need to knock out a sizable chnunk of reinforcing. For sure there are waves out there that could do this, but hopefully I am never in the same place as they are! The boat is also very light, which will make it easier to knock sideways, thus reducing the wave loads.
Rudolph, hull bottom is 2 x 400 db with a 200 wide overlap down the middle and a layer of 450 uni. Plenty strong, but a bit flexible. There is a bulkhead at each end which will stiffen it up. May need another in the middle or a layer of uni across the hull if it is going to dry out a lot. Much wider than this (400mm) and I would use foam without glass on the inside, then glass it after bending. Pretty sure the next one will be flat bottomed, with large solid glass radii, so won't be a problem.
Can you tell us more about the proposed keel, please.

I agree - let the sunshine in... but would one have to considre the structural strength of windows this size lying to a sea anchor and exposing the ww hull at an angle of say 30 degrees to breaking waves to have both bows meet the waves at about the same instance?
