I think the old style rudder system is by far the better system. If you do add the tiller extension the new boats will have to pass the stick behind the mainsheet.This is one of the great things about the early Waves. On the 2 Waves I have the rudders will fit off a 17 18 ect. and there are a lot of parts out there. Just change the tiller arm. I want be cutting mine down or buying the sorry new ones.
