Actully I used nylon, which is easier to work than polyester. I would not
use a stretch fabric, there would be no strength to it. All of the skin
strength comes from the fabic, not the sealant. If it streatch it would not
hold it's shape, and eventually the hypalon would crack and peel off. Do
not even waste your time with that idea.
If you are building a non-folder the fastest way to skin to to put a wood
stapling strip on the deck ridge and use rust proof staples from a marie
supply yard. You just staple it up the keel, and down the center deck
stringer and round a plywood "sub coaming". You then apply sealent, and put
on the real coaming on top of the "subcoaming" with screws. It is simple
and fast, and there is no stitching.
