I want to incorporate a centre console into the 4.3 mtr. Pacific dory that I am building. I am interested in foam as a means of saving weight. I have never used the stuff and am confused by all the foams avilable. Can somebody point me in the right direction regarding foam selection, methods etc? I well have enough 6 oz. fibreglass cloth to sheath it with. It will be a simle structure to house the helm, gearshift/throttle controls and a couple of instruments.
