In the Northwest, good heat is critical even during the summer. I had a Force 10 Diesel, since I loved the low profile "Charly Nobel".
At a boat show a few years back I found out that Force 10 made a conversion kit to change the Diesel to Propane. At the same time I changed out the alcohol stove for propane-also Force 10. The stove does not gimbal, but I have a Forspar "camping" stove that is gimbaled, and does the job.
I love the propane. Since I did all the work with the boat in the water, I made a propane enclosure to hold the bottle that mounts in the locker behind the head door, and which vents into the anchor outlet. I've got a Xintex sniffer in there. Mounting a propane locker in the rear of the boat would probably be utlimately safer, but I didn't want to give up all the space.
