Hi Ric. Yes, and thank you for that. I carried the jerry cans on deck the first few passages South and back North between the Chesapeake and the Caribbean, but never needed a drop of fuel from them. Finally gave them to a boat going transAtlantic. If I ever do an ocean crossing, I might add another tank, just not sure where. Kristy lists a little to port already, and is a little stern heavy, so the port deck locker and aft lazarette don't seem ideal. It may be most sensible to carry cans on deck on the starbord side, since I wouldn't need or want extra fuel once I crossed.
I also average a little under 3L/hr when motoring. I usually motor at ~2000rpm and motor sail at rpm enough to average 4+kts.
