older scot: rudder angle, jib track questions
I enjoyed participating in my first race with restored and newly rigged FS 1632 yesterday. We experienced moderate weather helm while beating in 8-12 mph. Sails are older Nichols but not evidently blown out (I'm guessing loose rig cut but no information on that). I'm familiar with sail trim goals (cunningham to pull draft forward, using vang to avoid oversheeting main) and the need to hike and/or ease main to keep the boat flat in gusts, but these efforts didn't seem to help the helm much.
I'm planning to measure mast rake and borrow a tension gauge in the near future, which may help. Also on the list is shimming centerboard.
But I was looking at the rudder and wondered if the angle might be an issue. I've had the experience of rudders on other boats kicking up partially when we run into weeds etc., and it produced a weather helm effect. If you see from the picture, it's angled back about ten degrees. The small notch visible in the upper forward edge of the exposed aluminum also seemed suspicious, as if it had been modified.
Relatedly, I read in Scots and Water about one sailor upgrading from the outdated (long) jib tracks. I don't want to replace mine, but I am curious as to how much shorter new tracks are and whether I should be using the forward or the after portion of my long tracks.
Thanks for any advice, and happy sailing!
