"Hull speed" is voodoo science

Hobie "cat". The hull speed equation is intended to apply to monohulls in
displacement mode.
The arguable point is really the definition of displacement mode, not the
veracity of the hull speed theorem. IMO, a Hobie Cat is on plane....(hell,
sometimes airborne)..when it is making better than hull speed.
A hobie cat doesn't plane. But it does break the hull speed "rule"
because that only applies to L/W ratios of around 3 or less. Hobie cats
are like in the 15-20 area.
