I am interested to know about the Cat Ketch 31 boats designed by HAlsey Herreshoff built in Florida and what improvements are practical, in particular a BATHING PLATFORM and ladder for the stern, a BIMINI, SPRAY HOOD, Wheel steering, holding tanks etc. so I shall appreciate it if anyone can point me in the right direction for photos or descriptions.
I think I remember seeing an article on this boat in 'Practical Sailor'
. Here I refer to it as the HERRESHOFF 31 (CAT KETCH 31) http://sailboatdata.com/viewrecord.asp?class_ID=5784
As you can see I don't have a whole lot about it. One of the best places where you mind find a fellow owner, or former owner that might have some answers to your questions would be cruisersforum.com. I wish I had a better depiction of this yacht, like something from an original borchure etc., but for now, this is the best I can do.
