I normally don't post a topic unless I'm at least 95% sure of what I'm talking about - I've learned that over the years posting topics on the sail trim forum. The forum is loaded with sailors "who know their onions" about sail trim and they're quick to pick up on misinformation.
Anyway, I've been watching the Olympic swimming event and noticed the men and woman are all on the tall side - don't see any 5'9" guys like me and I wondered why and thought it might apply to the length of a boats water line exposed to water. We've all seen boats sailing close hauled and so heeled over with most of the crew hanging over the side that you can almost see the keel. I never thought that was the way to sail a boat closehauled. My C30 likes about 10* to 12 * heel closehauled. Less and more heel translates to my boat speed falling off.
I'm not a scientific guy and state that in my book -- "If you want a scientific presentation that include intricate detail, together with a complicated formulae for hull speed, wave lengths and displacement/lengths ratios plus endless verbiage then this book is not for you". With some things I really didn't know why they worked but I knew they just did.
I'm just a common seaman and country boy living in Tucson, AZ but I think there's something about the height of these swimmers that applies to sail trim. Maybe some of you scientific guys can help me out but keep it simple because I get confused easily!!
