idasailor
I broke my rudder back in June on an O'day 23.
I have me boat in a lake with a nuclear station. The lake level fluctuations 8 to 10 feet each day.
So I decided to go with an Idasailor kick up rudder. It wasn't cheap!
But, I can say that since June, I've had it kick up at least 2x during sailing. It works great. They were really good at making sure I gave them the correct measurements, etc.
To be honest, that little rudder cost about 1/3 the cost of the whole boat!
