Jonnie, You need to go a lot faster! Karl, My rudder verticals were always longer anyway so Phil shouldn’t have as much a problem as others in this respect.

I've just looked again through morning breakfast boredom and I would like to point out it is VENTILATING not cavitating. everyone gets this wrong and it is annoying! Cavitation is when the water pressure gets so low that it vaporizes and can/does serious damage to stuff when this happens... PS.

To fix that you need to run the mainfoil deeper or add some height to your rudder vertical. This is I think why rudder verticals have been getting longer lately - people are flying the main foil really shallow and the rudder vertical simply runs out of length.

Thanks for tip on chopping the rudder down. It was painful demolishing your foil! Excellent, I look forward to seeing it! Thanks for tip on chopping the rudder down.
