That may work if you know what sail shape you are looking for in a given condition and also have a large capacity for storing and retreiving info on the fly, but if you are just starting out in a class new to you, or aren't sure what the sail shape should be, having marked settings is the best way to ensure that you are in the ballpark. It also helps shorten your learning curve.computeroman2 said:Personally, I would discourage using markings. For one thing, they won't carry over to another boat. You should use the guide in the above link and try to get it right by the look and feel. That way, you better understand what the sail is doing and you can carry your sail-trimming skills over to other boats.
The diagonal creases are telling you that between the two ends (clew and mast) there is not enough cloth.LPW said:ON the subject of sail shape, when i two block the main i get diagonal creases in sail running from the mast to the clew. Is there a control i should alter to get rid of this?? The cunningham gets rid of the creases but i thought i wasnt ment to pull on the cunningham until overpowered??
Thanks for the advice, ill try it out next time im out. Being a light weight I was thinking of upgrading the purhcase on my cunningham, but now i see a point to their not being that much purchase.49208 said:The diagonal creases are telling you that between the two ends (clew and mast) there is not enough cloth.
You don't want to pull on a LOT of cunningham until overpowered, but once you are two blocked, you need to pull the cunningham down just to pull the excess luff cloth down the mast. I typically pull it down just to take the slack out and then release in conditions where I don't want any cunningham on (A great reason to use 4-1 or 6-1 purchase in light air, as it lets you "feel" when you have taken the slack out vs actually tightening it)
Check your outhaul setting as well. To tight lengthens that distance between clew and mast.
