I think Hunter Boats (UK) have comprehensively disproved that twin keels have
to be slow.....its a case of designing them properly. If you think about it
logically with nicely splayed keels, when heeled over one keel will be way
out to windward giving a good righting moment while the other is close to
being vertical doing a good job of resisting leeway. Obviously extra drag is
a problem at low speeds but when you have an excess of power in fresh winds
then it would seem that properly designed twin keels can be highly effective.
