It seems a lot of posters are looking to justify their choice as the right one. Thankfully, we're all different and there is no right answer.
I have done 13 knots on a Catana
50 on a broad reach when it was blowing about 25. It performed well below what I expected but it was a charter
with ratty sails
and loads of amenites. I have hit 23 knots on a monohull
, surfing down waves when it was blowing 28-30.
My new boat will be a carbon fiber cat, launching in a couple months. It will be capable of very high speeds. I went this route
after chartering several different cats and finding the performance unimpressive. But I know a lot of people wouldn't trade
the comfort and space for more speed and that's fine. Personally, I love going fast and with a lightweight catamaran
, I can get a lot of speed and reasonable comfort. I cruised extensively on our Outbound 44 (max speed 11.5 knots downwind in 40 knots), The cat will have more space, be far more comfortable at anchor
and easily sail twice as fast as the Outbound in most conditions.
