Thanks guys, yes i well lubricated them really good, plus i do pull them up before the beach anyways.. I hope they don't snap when i'm sailing at great speeds that would suck! I guess i will keep that in mind and look for better blades to fit those castings.. I know a few of guys with H18s that use these rudders in my group. Do you guys think I would gain a knot of speed with these ? I did feel a little more increase in power in the little breeze we had. Who knows i will find out this weekend we all sail around each other and chase each other for fun, I would always get dusted and i felt that i was dragging something.. LOL But i have to say you guys know your rudders for noticing that one!
