Excellent! Thanks, A.H.

P.S. - when I hear the term semi-catamaran, a monohull comes to my mind...
So, putting these two criteria together, the rule of thumb would be:For a swath there are several rules of thumb, but basically if the waterplane area, Aw, divided by the displacement to the power of (2/3) is less than 1.5 it is a swath. Another simple one is if Aw< 2xDispl^(2/3)
if
Aw/D^(2/3) < 1.5-2.0
then it is a SWATH.P.S. - when I hear the term semi-catamaran, a monohull comes to my mind...
