I recently had a 3rd reef point installed on my Main sail. In the photo below I already have my first reef in. The new third reef appears at the sail numbers.
I worked with Pineapple Sails in Alameda and had a good experience. The staff were friendly and I am pleased with the work. Theirs is a full-service loft complete with a computerized fabric cutter capable of producing custom sails in-house.
Kame (pronounced “Cammie”) Richards is the owner and has served the SF Bay sailing community for a long time. I would be happy to return to their shop should I need additional help in the future.
