Sail trim
Sorry, but I still don't buy mast rake as the primary cause of weather helm. The amount of change in forestay length available at the turnbuckle simply can't change the rake of the mast that that much. I learned this the hard way after trying unsuccessfully to get rid of excessive weather helm on my H23.I firmly believe that sail trim is the way to go before you try anything else...for two reasons. First, the sails are the largest surfaces on the boat and they exert the most force. Second, sail trim adjustments are the easiest and fastest you can make,a ndifthey don't work, theyare easy to reverse so you can try something else. By the way, adjusting heel and centerboard depth are other simple ways to adjust boat trim.Simply put, lee or weather helm are signs of imbalance, so start by balancing the sail plan. Sheeting the jib in too tight will add lee helm. Sheeting the mainsail in too tight or excessive boom vang tension will add weather helm. Sailing in light air with insufficient heel will cause lee helm. Sailing in heavy air with excessive heel will cause weather helm. All these conditions can be changed in seconds.It's easy to sheet in too much, because once the sail stops luffing you can't really see what's going on. Telltales are cheap, easy to install and help sail trim immensely. Try some woolies on the headsail and ribbons on the leech of the mainsail. If the telltales don't agree with the masthead wind indicator, ignore the wind indicator.Next time you have lee helm, try any of the following adjustments. Do whichever is most convenient first, and combine them as needed to correct the lee helm.a) sit on the leeward side of the cockpit b) ease the jib a bitc) trim the mainsail in a bitd) harden the boom vange) lower the centerboard a bit moreSorry about the length of this post, but I think there are lots easy things to try before you start messing with the forestay. Good luck.PeterH23 "Raven"
