Great responses to the control freak quiz. There is a special group within the whole spectrum of sailors that I think I can help. Read on to find out who they are. Maybe your in that group. At one end of the spectrum are guys like me, who really want to know how to sail their boats and get the most out of them. We are not born with sailing knowledge so these folks go to any length to try to figure out how to properly trim their sails. This group comprises about 20% of sailors. Sailing is like playing golf or hitting a baseball. If you want to become proficient at either you need to follow a step by step approach and understand the dynamics of what is happening to the ball. In other words, I could feed a monkey enough bananas and get him to hit a ball but he'd never be consistent. On the other end of the spectrum is about 20% of the sailors. What they enjoy is just raising the main and rolling out the jib and calling it sailing, which it is. The boat moves through the water and they get where they are going - eventually. There is nothing wrong with that. They are like duffer golfers who just go out and smack the ball around. They enjoy the walk, exercise and they have a good time. They have no idea how the sail trim controls work and don't care either. The next 20% to 25% below the duffer sailors is comprised of folks who have varying degrees of sail trim knowledge, which runs all the way to expert but a lot of them picked up their knowledge here and there. Sometimes the sail trim changes they make work and sometimes they work against each other. This group is pretty confident in their skill level and it is hard to teach them new skills. They just sail along. The problem is "a man doesn't know what he doesn't know". It took me a long time to figure out what I didn't know about sail trim. Now here is the group I'm really attracted to. They are golfers that shoot just over and just under100. They want to improve their sailing skills but they don't know where to get the information. They don't have time to do what I did and go through 25 books, 5 videos and review over 100 sail trim articles from various magazines and compile all the information and then test it on their boat to see if it works. So what do they do? They experiment, talk to their neighbors, try racing and try to find out what works. That's learning the hard way. You'll never shoot under 100 using the self taught method. If you could, you'd be shooting in the 80's. So how can I help this group? I could start explaining sail trim in this forum but space doesn't permit that. Here's the next best thing. I've compiled just about everything there is to know about sail trim into a book and a chart, which you can purchase at the ship store on this site. You've seen the comments of some of the people that have purchased both items. I guarantee that after digesting that material you will know about sail trim than 75% of the sailors worldwide. If you don't believe me just ask some of your dock mates to define draft depth and twist and explain how they work together. Ask them to also tell you what sail trim controls are used to adjust both items.
