Ross 930 Rudder Profile

Recommended Posts

The 'ship is going to get a bottom birthday and while I'm at it I'm thinking to tidy up the rudder and try and get rid of the hummmmm.


The rudder is still the original plank, but now stood up perpendicular (rather than following transom line). So I have to cut off the bottom to level with waterline, but I'd like to make sure the profile is good too.


What's the appropriate profile for a rudder on a turbo'd 930?

Stu built a new rudder when he had Ballistic, I think he is All Fired Up. If you search under foam profiles then it can be found but the photos haven't come through, his rudder set up was different to normal 930s though.

I have a copy of some 930 plans at home with has a rudder profile on it. I can hunt them out for you. May be a starting point.
