Welcome to the group.

The core is 12mm Divinycell, 80 kgs per cum m.  The surface area of the ww hull, bunks and cockpit is near enough 32 sq m, so there is 384 kgs of buoyancy.  I will probably chop the bows off and replace them with polystyrene at some stage (hopefully before, not after I hit something), which will increase this considerably.  There are also the hollow beams which will add some flotation.

just checking into this group. Thanks for all this fantastic stuff. My
interest concentrates on the Solitarry as a very fast boat with off
shore capabilities. Looking at the picture files the first time I
noticed in the file "Solitarry 7m ww hull" that a core? for the
infused laminate seems to be pink high density foam? I have problems
interpreting what I see. I probably got it all wrong. Anyway a
question: would the ww hull with the core material have positive
flotation? and if yes - how much approx.?
