Use a good timber yard and they'll have a variety of lengths from the wholesaler, and we ideally need an uncut three-metres for each uppermost spar in the pontoons. Our keels are effectively on the topside, unusually for boats.
Accordingly I figured we'd need a pair of ten-foot (3.0m) inch-square (25mm) lengths, although we are likely to use nearer nine-feet for each.
We also need four eight-foot (2.4m) spars for the remainder of the frame, one for each pontoon and two for the centre-deck assembly.
The timber has cost less than £100, which does not usually go far when you're into sailing anything nowadays ~ so well done me.
The spars are stock redwood and planed all round... or square, actually.
