Hi all, I'm having an issue with my rudder that seems to be getting worse. When the rudder is deployed it seems that it won't stay down. I've had to resort to pulling on the down lever with my right hand all the time, while using my left hand for the rudder controls. If I don't keep the rudder pulled down it slips up and doesn't work as effectively. It looks like there's a groove where the rudder latches into the hull (see attached photo) and the rudder doesn't stay in that groove. I hope that makes sense. Any help would be appreciated.
