    If theoretical Hull speed for a displacement vessel is determined by the sq. root of the length of the water line times 1.34, then what is a displacement vessel called which can exceed it's Max. Hull speed.

    The most common term is semi-displacement, but I think semi-planning is more accurate for a boat that is almost planning. You choose and there will always be someone around to disagree.

    SailDesign Old Phart! Stay upwind..

    Either what duluth says, or you could call it "skinny", since a slender vessel will exceed it's "hull speed" quite nicely, thank you.
    Be vewwy vewwy careful about using the expression "hull speed" in these parts, as there are pirates everywhere who may pounce.....
