I want to extend my fiberglass rudders about 8". What is the best way to do this?
Also, I dont think my rudders are stock. I have a N 5.7 and the rudders are straight so that when fully down, they angle back paralell to the transome. very hard to steer under load. I didnt realize there was a problem until a friend got a 5.8 and I noticed that his rudders curved forward below the hull.

Could I somehow take an impression of his rudder and extend it and add to my existing rudders? would I be able to make it strong enough?
