Would this be for the 2007 model (Getaway) year by chance?
If so, how to resolve this? Would warranty still apply? Are rudders the issue?
The symptom of a rudder problem on a Getaway or a Wave is a heavy weather helm on one tack and lee helm on the opposite tack. This is due to an asymmetrical shape of the rudder blades. One side is sunken-in when the plastic cooled. You can see this by placing a straight edge along the sides of the blades. You should see a hollow on one side that is deeper than the opposing side of the same blade.
If this is present and you are the original owner, we could consider a free replacement set of blades. You would have to file a warranty claim with an authorized Hobie dealer. If you are a second owner... we can consider a highly reduced cost for replacement blades.
