drbob 0 Posted May 14, 2016 Share Posted May 14, 2016 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?

erice 732 Posted May 14, 2016 Share Posted May 14, 2016 little known fact U2's album was written when adam clayton was experiencing problems with his stock rudder Helter Skelter being about the difficulty helming downwind at speed and under masthead gennaker Desire when he decided to change from stock Silver And Gold about the cost + I Still Haven't Found What I'm Looking For when he finally gave up changing naca profiles Link to post Share on other sites

armchairadmiral 411 Posted May 14, 2016 Share Posted May 14, 2016 Why does the rudder bottom have to be level with the waterline ? Naca sections are obvious....why reinvent the wheel and rediscover fire ? Link to post Share on other sites
ballystick 79 Posted May 14, 2016 Share Posted May 14, 2016 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. Link to post Share on other sites
