I've got some folks working on the downed oak tree, so will try to add some thoughts.
People with Wallas stoves either swear
by them or swear
at them because of their sometimes problematic/temperamental nature, but they're a very viable choice in cold climates.
Alcohol stoves are simple and cheap, but don't work very well for all the reasons listed above.
Alternately, you can use a portable propane cannister stove to cook on, and it can be used inside or outside the cabin. On my Sea Ray with it's combo electric (120 v AC) / pressurized alcohol stove, I also have a cannister Coleman stove with two burners that I use instead out in the covered cockpit to avoid cooking odors inside the cabin. One of the two burners has a dual burner that has an interchangable grille / griddle top for steaks or pancakes, etc. Very flexible!
In my C-Dory, I have a propane system with a Wedgewood three-burner cook stove and a Force 10 Cozy Cabin propane convection heater with 2 fans and both propane and carbon monoxide detectors for safety.
Some folks are afraid of propane because of the explosion hazard, but with care and diligence I find it a great system. Nothing else produces cooking and cabin heat anywhere near as fast or as plentiful!!!
Some folks also use propane cannister heaters such as the Mr. Buddy models, but they vent the combustion gasses directly into the cabin and must be used cautiously with a window cracked open for positive ventilation.
A portable 1500 / 750 watt electric (ceramic is safer than a hot wire type) heater is an absolutely great (and cheap) alternative everyone should have when at a marina and on 120V AC Shore Power!
Another choice for cooking is the Magma stainless steel BBQ models. These are mostly propane powered, and must be used out on a cockpit rail and are pretty much BBQ grilles only. You could put a pot or pan on one of these grilles, but the heat transfer wouldn't be very efficient. BTW: Hot charcoal on a boat is like smoking in an enclosed gas filling station!
The alternatives are just about endless, but unfortunately the space aboard any of the C-Dorys isn't. One has to decide what's best for their style of boating and climate expectations.
There are tons of photos of different stove/heater installations in the
Detail Photos of the Cabin and Interior section of the Forum.
