These boats are interesting as they seem to break the rules. The ballast is laid in the bottom of the
hull and the righting moment on these boats is very low but because they don't have a
keel (as long as the center board is up) then instead of tripping over the
keel they tend to slide sideways. I was visiting Jimmy Cornell in the
South Pacific and he said that they also were a treat to sail under
spinnaker as again the
boat would not broach it would simply slide sideways for awhile and then straighten out. The downside(no pun intended) is that once inverted they don't have much of a righting moment and need a wave to get them upright again which is not cool. The good news is that they made it off safely and everyone is OK
