Probably rudders. Depending on the year and rudders supplied by Hobie, they may both bend the same direction. Best bet is to see if you can find some EPO rudders off an old TheMightyHobie18. Totally legal for racing and much stiffer and dependable.

There are boats here for charter, by the way. Love to have you join in the fun down here and get the bug. I will be running races and have an extra boat and it has a trailer.
