Why are the bows of each float not level with the bow of the principle hull?
Good question to which there is an important answer. The fact that the floats are set back from the main hull makes the boat handle better and makes it safer. It is becasue they are set back that the boat behaves more like a monohull when turning. It is not necessary to use the jib to turn the boat as it often is with a catamaran. The boat turns around the centreboard really nimbly. It is safer because the positioning and shape of the floats drastically reduces the likelyhood of pitchpoling. Floats are set back from the bow of the main hull.
