Curious to know if anyone has tried tyvek. Have used my sail 30 plus hours this summer and had it in wind of 25+ mph and cannot detect much stretch at all. Only area showing much wear is the mast pocket. Seams are holding together nicely, no popped stitches, corner eyelets showing no localized stretching. Sail still hangs at original height and have not had to adjust batten tension. Very happy with durability versus cost.

Seventeen layers sewed together, mast pocket to sail. Domestic sewing machine.

Rivet used as batten stop.


Battens made from 1/8 inch thick hickory strips and kind of rubber cement used on
seams.
