Being a recreational sailor on a freshwater lake does have its advantages. I don't have to have the "ideal" shape to my sail to enjoy a good wind. But if you are tinkering with your tention, I assume you would want to have more than one set of battons, or at least using battons with taper.--Too much monkey business for me! Just hand me another beer, please.
And with fresh water, when it comes time to clean the boat, you use the lake water to wash and rinse the boat. Dirty sail??? Just dump the boat over, then right it to dry.
Life is easy here.(But the winters are...well...life always evens out in the end.)
