The Sobstad Cleveland loft makes very good Dacron mains and Kevlar
#1s for very reasonable prices.
Also, don't overlook Santa Cruz Sails, in Santa Cruz. If I'm not
mistaken, the boat that won the nationals this year (Baffett) used
Santa Cruz sails. I believe the second and third place boats used
Quantums and the fourth place boat, Pineapples. If you want to use a
pole launcher on the boom, I would recommend getting a loose footed
main. All the Detroit boats and many of the SF boats use loose-footed
mains.
