Time to get started on the Foamie’ boat !!! ... I have the mouse boat plan and would like to make it -12’ long and < 48" “ wide ... Guess the easiest thing is, to draw the plans out on kraft paper full size on the floor , and use a scale factor (150%) for the larger size needed ... Since foam’s homogeneous (and will be covered with a skin) , it should be no trouble to just butt together foam material for sides and bottom > 8’ long... laminations will stagger the splices.
Thinking we’ll likely use 1” foam and then double that with a lamination of another piece of 1” foam ... Properly skinned in and out it should be “strong enough” even for my “large frame” ... ..
