I'll recommend that you stay away from the Coleman gasoline stoves for onboard use. They rely on the owner to hand pump pressure into the gas tank in order that the fuel can atomize correctly. When the pressure begins to go down, the flame blossoms into a higher, dirty yellow flame. If this happens when your back is turned, you might light off curtains, etc. Also, refilling the one quart gas tank through the 5/8" filler hole is not a safe activity on a rocking deck. Finally, the stoves can be a bit finicky as they get carbon buildup and wear on their valves. I had one experience where a Coleman gas stove lit off with a 12" high flame. Luckily I was outdoors and could simply step back a little and think through getting the fuel shut off.
Propane creates water vapor when burned. It will have dew hanging on your cabin walls after cooking a meal. In the RV world, propane appliances are externally vented, and stoves have a forced-air hood over them to exhaust the water vapor.
