Been wanting a new rudder for years. Can't wait to try it. The boat is in the water and the trailer at the shop having new fenders installed, so unless I don the wetsuit and wade in, I'll have to wait.
Carl,
I installed one of those on my SunDayCat two seasons ago.
Helpful at slow speeds or large angle of attack, such as around the dock.
Be cautious that the mounting hole is in the right location.
Mine was not pre-drilled, took some care to get it properly located.
The head perimeter was shaped differently than the Com-Pac rudder was.
Regards, Roland
