There is a clear distinction between a displacement hull and a "semi-displacement" hull. A pure displacement hull just digs a bigger hole and pulls up a bigger wake with very little additional speed after it gets to a certain point. Any one that talks about going 9 or 10 knots cruise on a 36-40 foot waterline is clearly in the semi-displacement mode and burning way more fuel than I can afford. Not that 15 knots would not be handy at times......
