Hi Tod, Thanks for Busca's mainsail measurements. I took my main in last Saturday to have the second reef point added. While there Joe, at the sail shop, stretches the sail out and stakes it down with awls. I believe he said my first reef was at 38 inches. So, he doubled it for the second to be added. Sounded logical to me so I said. Do it. The cost here in the SF Bay area for such work is $125.00 case anyone is pondering it. And, it's probably less than that anywhere else. I'll take the measurements you made and see him about the slugs before he gets the first job done. Todd, did you notice the picture of you, John Edwards and Bob Eeg sitting in the cockpit of Busca.
