Ah, Bob - They're talking about powerboats there, not sailboats.

Almost every reference to "semi-planing" is for powerboats, not
sailboats. Its becoming clear: what you like about your bendy is that
it handles like a powerboat!

This is not to say keel sailboats don't on occasion "semi-plane" but
there are only a few (like the 60's) that can sustain that for any
significant period.

It seems that a few folks have heard of semi-planing sailboats!

Volvo Introduces Five Sailboat Engines - August 08, 2005
With eight engines ranging from 12 to 180 hp, Volvo Penta now has the
market's most modern and complete engine range for displacement boats
and semi-planing boats.

And PLEASE read The Nature of Boats, Loco. You might learn a thing or
two about sailing and semi planing disp. hull design.

You've exposed more times than Scotty Potty's wang at the All-Gay Expo!
