I stand by my numbers. I say they are
a fair representation since the "modern"
multi-hull is only about fifty years old

Wow, what an ignorant statement.

The modern multi is NOT 50 years old. I'd say less 20. In fact, in the last 10
years Multi's have enjoyed a gigantic leap in ability due to new builing
materials and techniques.
A modern cat is quite a boat.
