pre bend

[Capt Ken]

I have a 1990 Catalina sailboat. one piece keel stepped aluminum mast. Not sure who manufactured the mast. At a mast tuning seminar I was told all masts should have some aft pre bend in them. The speaker was a rep from Selden very familiar with the masts they supply, but didn't seem quite as knowledgeable about boats with my mast. Winds where I sail are usually light, 5-10, with an occasional day in the upper teens. If I should have some pre bend, how much? The mast extends about 42' above the partners.
