I was part of a discussion on another network where the subject was mast rake (which has been beaten to death here and I don't want to get into it) and it made me think about how much is too much and how most skippers are not specific as to the amount of adjustment they want their crew to make on a particular sail trim control.For example, a skipper will say "give me some outhaul". Does that sound like you??When I hear that on boats I'm on I wonder a couple of things. The first is WHY does he want to adjust the outhaul in the first place? Assuming there is a good reason, the next question is which way and how much? The next question I have is what about the other controls? By that I mean the outhaul is a factor for draft depth along with mast bend. The outhaul also is a factor for draft position along with the boom vang, cunningham, and mainsheet. Touch one of them and you have to do something with the other ones.To put it into simplier trms, if your car had a carb with 4 jets would you adjust only one of them and expect 100% performance? Obviously, you wouldn't but a lot of skippers adjust only one control for draft depth, draft position, twist or angle of attack and wonder why they the boat does not perform.Do you know what controls are used to adjust draft depth, draft position, twist and angle of attack for the mainsail and jib? Do you know HOW MUCH adjustment to tell your crew to dial in for each point of sail and wind condition? Dirty Harry said "a man has to know his limitations" and if you don't know the answers to the above I can help you. All you have to do is ask. On the other hand, if you do know the answers then do your crew a favor and give specific commands.
