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?

My existing I do like but it was a quickie build so having de laminating issues so I'm thinking of building a new rudder. Another boat was also thinking of a new one but I can;t quite remember who, I think it may be a turbo that is worry free ;) I'll suss.

 

Maybe it's time a mold was built.

 

My existing is hum free and is very quick to tell you when you have the boat trimmed badly, I do like it.

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.

 

 

that would be a good start thanks - I can at least get the barn door fair to original, eh

I'd be very very interested to see those if you can find them. Thanks Fella.

 

I'll corner Gazza FNG when he comes to work next, he's playing with the lads next door at the moment....in the work mate sense not the bad touching sense .... or at least we hope so ;)
