Maybe it was a nonsuch they make a few different lengths
I think this gives an idea of how much room a 26 non such has internally I still like the freedom 33 cat Ketch it would be a great easy sail for an old bloke
There was a 38 cat ketch I think it was called black magic years ago it circumnavigated many time around the earth think some one wrote a book on it while they were sail cant quite remember right now very agile .
Gary Hoyt was very innovative originally they can out with the wishbone rig
They have two problems to keep an eye out one is balsa core and other is the carbon fibre masts some have been repaired now. I think it was some thing to do with the original way the mast was wrapped on the finally wrapping some had problems
The balsa core is only a problem if some one cuts a hole in the deck and it dose not get sealed up properly and water gets into the sandwich core
