Re; Birdwatcher Junk Rig
I made the sail from a $10 blue polytarp. The luff and leech are
reinforced with nylon backpack cloth. Camber is created with broadseams
(darts actually) at the battens. The battens are two piece (spruce)
with the sail sandwiched between and held together with screws. All
pretty low tech.
