Which Moody 36? The old Primrose design from the 1970's, or the modern one designed by Bill Dixon?
The new one has a very modern, typical Bill Dixon underbody, with a bulb
keel, and should be an excellent performer (I don't much like the
saildrive, but that's what you usually get nowadays in that size category).
The old one will be slower and less weatherly. They have fin keels, but rather low aspect ones. A lot of progress in
hull and
keel design in the 1980's and 1990's. Although this guy:
Living aboard around the world circumnavigated in one.
All Moodys new and old track well in straight lines. They were never built with the flat bottoms and wide sterns of the French production
boats.
