As for the comfort of cats, I did a delivery of a 50 foot cruising cat to Vanuatu a few months ago and was shocked at how uncomfortable it was in a seaway. I have sailed on smaller monohulls all my life and thought that it would be more comfortable and faster than a 35 foot racing mono. This was simply not the case.
So much leeway in waves that what should have been cracked sheets was on the wind.
Not impressed. Any half decent 50 foot keelboat would have been faster safer and more comfortable.
The cat was great once there with lots of room so horses for courses I guess.
Yep, some of the condo cats are terrible sailing boats. OK downwind, and living at anchor. There are good cats too though, same as there are some very poor sailing mono's and good ones too!
