Deck in sandwich composed by 8mm marine plywood,20mm PVC foam 75 kg / m3, biaxial glass fiber

The hull is made of sandwich composed by 10mm
plywood, 20mm PVC foam 75 kg / m3 and quadriaxial
glass fiber laminated under vacuum with epoxy resin.

The keel weights 3200 kg and is composed by a 70mm
thick solid steel blade, lead bulb and wooden casing
(draft 2.15mt). The keel is laminated with 3 layers of
600g/mq biaxial glass fabric laminated with epoxy
resin.


Your boats designs seem to be on the race side of things and while there is no detail of how the plywood and wood is used in the layups

Plywood cores have a well deserved BAD long term track record in the USA
