Hull sheets/plating
For Jordan: (note 2) Here I can get 1/8" "Luan" 3 ply, fairly cheap for a 4 x 8 sheet, at the DIY. Luan is a cheap form of mahogany, and is disappearing. Beware of substitutes, such as pear, balsa is expensive and hard to find here. Look up strip canoe construction, almost like our boats. Adapt. Did this help? Kirby 😐
