Both rudders were replaced Feb/Mar 2009 with new ones purchased from the Indianapolis dealer, Sailboats, Inc.
I had not experienced weather on one tack while lee on the other. The boat only was used a couple outings a year recently and I remember two outings ago it seemed to have a little weather helm on one tack and a lot of weather helm on the other. During the last trip I thought about making adjustments to improve this, but not until we were already at the gulf and without proper measuring tools, etc., and not remembering which tack had the heavier helm. Ultimately, before launching we made a slight increase to the rudder rake on both but don't really know what the result was since we didn't really have strong winds the entire trip. We had maybe 12 MPH wind max during the 4 or 5 days and I didn't notice anything uncomfortable or disturbing with that wind level. I had not really considered anything significant going on, assuming some minor adjustment needing correction.
If the rudders do have a warp I suppose the only real solution is to replace them. If they do, I am wondering 2 things: Since this was a known issue with either design or manufacturing, would Hobie consider helping you out somehow? And, in the meantime, after checking everything else too, if you are feeling some lee helm on one tack, could it be improved by identifying the offending rudder and reducing rake on that one rudder?
If you want to discuss further, feel free to give me a call/text/email. Otherwise, I hope you are enjoying the boat.
PS. I am working on changing my user name but haven't figured out how just yet.
