Twin bilge keels?
Reasoning, Schmeesoning. Just comparing the ride performance concerning roll behavior on my previous ComPac and Cape Dory compared to my current Westerly Centaur. With the windward keel rising up toward the surface of the water, creating what could be compared to having rail meat lining the rail, and the leeward keel dropping deeper into the water, the boat rolls less. My wife rarely accompanied me sailing in the previous two boats we owned,Too Scary, however she is now comfortably relaxed sailing in all kinds of wind conditions on the Centaur.
