However, there are games played with multihulls so that the waves from
one hull cancel the wave from the other. For one thing, this must be
considered to understand how the chop will slap on the underside.

However, advanced work has been done on more complex configurations of
three or four hulls with an eye towards high speed and efficiency. I
don't think this has led to any recreational sailboat designs.

it was shorter than the main hull, it would be a big drag.
