M_Boats: 80% jib

Don Yager sent me a description of the 80% jib he built for Tom Smith. It sounds "bomb proof" and of excellent quality. He said I could use it to sail back (up wind) when conditions did not permit use of an outboard, too much wave action I presume. Tom or anybody, have you used just a jib to sail to windward in blustery conditions? Seems like with the lee helm generated (?) you couldn't point very high with just that jib set. Is that "80" cut high enough so you can see under it when heeled over? It is pricey but having been blown down wind from my take out point at one time (was not flying a jib, just the main on my 17) I know that isn't much fun. fair winds, Tom B, Mont.17 #258, "AS IS"
