Hi all,

on Int.14' Skiffs Lindsay Irwin uses a twist grip type tiller extension to adjust the angle of the vanes on the bottom of the rudder blade. Angled down to lift bow pull transom down downwind, angled up to give lift to transom upwind. He swears by it and claims it is easy to operate once set up. But it must create more drag as it has more surface area than standard blade and when used to trim boat must create drag, I guess not as much as transom dragging or bow under water though.

Yet again played around with this sort of thing on sailboards years ago, but found for speed you couldn't beat a properly foiled straight fin with no extra bits on bottom. Of course sailboards weren't battling nosedive or transom drag though.

Maybe I will talk to Linsay some more? Definetly would be a weed catcher though a big problem on my home waters.

Regards Gary.
