LIST OF MATERIALS - ALUMINIUM

Sheet thickness can be from 1.6mm to 2.5mm, to suit the properties desired for the boat. A thin sheet will give lightness but be more difficult to maintain fairness during construction. A thicker sheet will add weight but give a more robust boat. Hull weight using 1.6mm sheet will be about 26kg (57lb) and will be about 40kg (88lb) with 2.5mm sheet).
