Glad to hear that you love your Garhauer vang! Maybe you could answer another question I have? The reason that I am putting a vang on in the first place is to be able to adjust sail shape, of course, and to eliminate the topping lift. Not having a vang currently, when I am sailing off the wind, the boom rises and the sails bag and rub against the shrouds. Also, my boat has much weather helm when sailing on a reach and broad reach and I am hoping to reduce the amount of weather helm by flattening the sail and thereby catching less wind. I don''t expect the vang to be a cure all however. Reefing to reduce sail area would be more effective I am sure. How has your vang improved the sailing on your boat?
