… he really knows what he's doing. Florida Rigging is your best bet, they may get pricey, certainly more than the salvage places you've mentioned, but you will not find better service & product in South Florida. And if you can deal directly with Pete usually you will get an excellent price. He's great.
Whatever you do … DO NOT GO TO OR USE MACK SAILS !!! Like the saying goes … Go try Mack, You'll be back ! They suck, and have no idea what the hell they are doing.
Good luck, cheers, John
