My last boat was a Cartwright 36 pilothouse cutter
and I agree wholeheardtedly with all of the positive comments about pilothouse designs. They allow you to keep out of the elements to steer in bad conditions, to have the chart table/radios etc. not only beside a helm
station, but also out of the elements. Furthermore, pilothouse boats usually allow the diesel
to be mounted under the pilothouse sole, allowing easy access for servicing and repairs
I have no personal experience sailing any of the boats mentioned above (although I would consider the Gulf 32 a bit small/underbuilt for a circumnavigation). A boat I would highly recommend, however, is the Corbin 39. Incredibly strong construction, very good sailing performance, proven offshore
capability and good visibility from both inside and outside steering
stations as it is a flush deck
forward. This is, in my opinion, extremely significant as many pilothouse boats require the helmsperson to stand up to steer when in the cockpit
(where you will be most of the time).
My Cartwright was also a flush deck
forward (and very similar in design to the Corbin, but without the canoe stern). An additional advantage to this design is that the relatively small coachouse permits much smaller fixed portlights
that do not require storm shields.
Other boats that have a similar design (flush deck with small pilothouse) include the Endurance 35, the Kingston 35 and a series of Ted Brewer designed double enders betweem about 38 amd 48 feet that were built in Orient in the late 70's, early 80's (and whose name now escapes me).
Good luck in your quest!
