Like a Wharram
they have more wetted surface do to the V hull
shape but the amount of boat
in the water
is a matter of displacement
, not the number of hulls so there isn't really a drag penalty there. Wave interferance between close hulls is a more likely candidate for drag. If not over loaded though, a Piver
can be fast off the wind
, nothing like surprising the unwary with a speeding box!
