It is a 2001 27 Open with 200 HPDIs, Generator, AC, forward canvas enclosure, cold plate system, auto pilot, and 12kw Furuno Navnet system. Cruise 30-40mph @ 2mpg, WOT is 50mph at about 1mpg.
It is the only one I have found set up even close to this. It makes it a little easier to step down from the 60C.
