A rudder that is continuously providing lift to counteract weather helm will create more drag than one which is not, BUT it will reduce the lift and drag from the centreboard. |

The rudder will always have drag, just like the centreboard. A light helm does not mean no drag, it just means it is better balanced. Edited by Peaky - 28 Dec 11 at 10:51pm |

That's blowing a hoolie on our lake! The other week the race was run (by popular request) when the only ripples were caused by fish jumping and ducks swimming! (and it was foggy). I was glad I was on race duty that day. I dont recall how many boats had their clew outhaul on hard though. |

(some) pond sailors will sail if there's one wind ripple per square metre of water's surface or less, where in tidal waters you 'd just be being pushed around by the tide

exactly keeping flow attached , it also depends, as you say on the rig - with the extremes of the laser / topper style shroudless una rig at one end and the all singing all dancing 27 pieces of string of a merlin or somesuch at the other as to what influence the outhaul and the cunningham has - basically by what opposes it's actions

Kevin Haynes was doing that in the 70s, which is recent on a geological scale of course ![]() |

Plus if a gust hits when the boat is heeled to windward, as it comes flat it is in the best position to accelerate from and thus more speed and height!

One of the Rooster vids goes into it in some detail. Easier to see it happening than to explain, at least for me...
