i have been told by the manufacturer and read accounts online that self-steering wind vanes do not work on multihulls:

they could not explain why. i'm guessing it has something to do with the large difference between true and apparent wind due to the high boat speeds, as what else is different with monohulls. but it is not clear to me why that would be a problem.
has anyone had experience with such a system? or have any idea why it doesn't work on multihulls?
they draw NO (zero) power! a beautifully clever idea.
