As most people know, a bulbous bow gives speed/range advantages on displacement hulls. There are already several yachts built with a bulb, but there are more built without one. Maybe because the protruding bulb is of more trouble than benefit as it can catch both debris and anchors?
Whatever the reason, I once came up with this idea of an integrated bulb. In my opinion a bulb on a yacht has one major advantage, to reduce pitching. Both at anchor and underway there is a much nicer movement with a bulb. To achieve this you dont have to extend the bulb in front of the hull, and I am pretty sure that a certain speed improvement will take place anyway just because the yacht is going with less pitching which otherwise would slow her down.
The exact shape of this bulb remains to be tested, and as always with a bulb, the stern has to get more buoyancy to get the right longitudinal balance.
Remember where you saw it first...
