How big are you talking about?
We sail on The Neuse, in North Carolina
, Which is very wide at the mouth where it opens up into the Pamlico sound. I see cat boats here, but having never sailed one, I would worry about being able to effectively reduce sail. There was one docked next to us when we went to Ocracoke
on the Outer Banks
a month or so ago. With the winds blowing 20+, I am sure they had to ref from the get-go. It was a Nonsuch 30, if I recall
There are plenty of shallow draft
boats that are sloop
riggged, if that is what you are after.
One of the coolest 35 footers I have seen on paper is the Holby Clearwater 35, designed by Craig Walters. Draws something like 1ft 10 inches with keep and rudder
