A little problem I have from time to time. Going upwind the boat will sometimes not just lean over at maybe 35 degrees and stay there and sail along like that - like I would expect it to - like it did at the natls, thank goodness. What it does instead is lean over at 35 degrees then pop up pretty much vertical then lean back over then pop up. This happens over and over like clockwork every couple of seconds. It is definitely not caused by a windshift or change in wind velocity.
I figure there is some sort of dynamics happening where the sails load up then release. There is nothing that looks odd in the appearance of the boat or sails that might cause this. The boat is steering itself on a straight course and bobbing down and back up. There does not seem to be anything ridiculous that I am doing in the setup/tune.
Has anyone run into this and figured out what caused it?
