Sloco's ignorance knows no bounds!
He doesn't even know what a semi-planing sailboat is!

FOR A POWERBOAT
THE SEMI-PLANING HULL

The typical semi-planing hull is a development of the pure
displacement hull - with sharp and deep forward sections fairing into
full rounded aft sections. The major difference between displacement
and semi-displacement hulls is in the buttocks.
On a displacement hull, the buttocks will run up aft while the
waterlines are coming in toward the centerline. If the desire is for
more speed, both the waterlines and the buttocks must be straightened
to reduce the tendency to squat. A semi-planing hull is essentially a
displacement hull with straighter buttocks ending at a broad transom
that has some immersion.

FOR A SAILBOAT
Rather a function of ultimate weight limitations, the semi planing
sailing vessel has no lifting keel and has a flattened hull section
that will lift the forward section of the boat. Weight and drag aft
disables full plane characteristics, but wetted surface is
reduced.


While wing keels have been given some credit for lifting foil
characteristics, it's a minimal effect on most boats and the flattened
forward underbody is actually behind the vessels ability to keep the
foward section aloft.
