Its highly dependant on a number of factors, the principle your broker

20th century(long and skinny). The the planning hull was developed
which shattered all the big boats dreams!! To answer your question
maybe up wind they both do the same speed but on a beam reach i wold be
surprized if the cat didn't win.

Cats generally do not point well. While they might have a a good SOG,
their VMG is wanting.

This is a generalization that doesn't really hold anymore. A number
of the newer cats point reasonably well. The PDQ 44, for example, in
16 knots true will tack through 84 degrees while doing almost 8 knots
for a VMG of 5.9. Reaching, it will do 11 knots. In stronger wind it
does even better.
