We have raced against monohulls quite a bit, and it is a myth that catamarans cannot point as well as monohulls. We can point at least as well. A Hobie Wave can point with Sunfish and Lasers. Any of the modern 18-20-foot catamarans can point with a Flying Scot. The difference is that we have to go a little slower than we normally do, in order to point as well as them.
It is not that we can't point as well as the monohulls -- it is that we don't want to. On a mixed starting line of monos and multis, we certainly can hold our own. In fact, one of the single biggest things catamarans can do to impress monohull sailors is to outpoint them at the start. For some reason this impresses them far more than our superior speed, because it busts the biggest misconception monohullers have about multihullers -- that all we can do is reach.
