We did look at the two SNs for sale in Martinique. The one with the Mitzubishi engine has been on a mooring, untouched, for a year and a half and is essentially a complete fixer-upper. If one wanted to undertake that the price would be negotiable to rock bottom I imagine. Definitely not something we would touch.
The other one was as described: clean, well-equipped and maintained with lots of upgrades, (perhaps too many).
In the end we decided we wanted more room aboard, and more speed, so we have been shopping for a Super Maramu and still haven't found the right one.
