This may be too late, but we are currently cruising on a Mariner 39. Absolutely great blue water boat. This boat has been to Tahiti, Alaska, and Peru, etc.
Lots of room, really, for two people and probably more.
Well found boat, sails well for a cruiser.
Also check out the Mariner Owners Net. Forgotten the web address so use Google.
