I just got an Idasailor Rudder
for my 222. The Idasailor 222 kickup rudder assembly is actually lighter than the one that comes on the 222 from the factory (there is a lot less material there). Besides it is a much better design. Not only is it a true foil shape, it actually kicks up if it hits something, unlike the original that has to break the rope free from the cleat to kick up. All in all I am very pleased with it, however they are not cheap. - chuck D
