Just got back from a week-long Sailmaking Fundamentals class put on by the Northwest Boat School in Port Hadlock, WA. See them at www.nwboatschool.org. Searched for several months before finding them. Wanted to gain a little self-sufficiency in repairs, maintenance, quality evalutation, etc., and got it all and then some at this not-for-profit school. Check it out, I highly recommend it!
