Yes it's true,
Sleeping on the boat while it was on the trailer (boat is unable to weather
vane) the wind came up pretty strong from the stern. Our CO alarm did go off even though the heater was outside. We finally figured out the wind must have been blowing across the heater and up to the weather boards allowing a little exhaust in?? Turned the trailer around, aired out the boat, reset the alarm, and didn't have any other problems. As long as the heater is outside, and I have the CO alarm inside I feel comfortable. But that's just me. You have
to make your own decision. I know a lot of folks that "crack" the hatch and use things like Origo heat pals or Coleman catalytic heaters inside. That I wouldn't be comfortable with. You'll have to make your own call.
Gary's advice is sound. You can't get CO poisoning if you don't make any CO!

Yes, a big by-product of combustion is water and the way to avoid getting the cabin walls and overhead covered in condensation is something like Sean's solution or some other vented method. Someone did a stoichiometric equation once, demonstrating the amount of water produced per pound of propane....pretty interesting: With perfect combustion of propane and oxygen, One Propane molecule five oxygen molecules C3H8 + 5O2 becomes (sorry about the lack of subscripting) three carbon dioxides four waters 3CO2 + 4H2O Or, put another way and figuring the weight of the molecules, if you burn a pound of propane you get over 1 1/2 pounds of water! (the increase is due to the oxygen that joins in) Of course, that is assuming perfect combustion, which you won't quite get.

On my CDory, we use a Wallis diesel heater that vents to the outside of the boat. This is clearly too big for anything but a M23, but you might look around to see if they or a competitor makes a similar model in a size that would be appropriate for a M15 or a M17. Caveat... The Wallis is a fixed mount, so you would need a dedicated "galley" area. With the lid down, there is a small fan that runs and distributes air in the cabin. With the lid up, it serves as a very good stove. To conserver power, we use an eco-fan (creates its own electricity from the stove's heat to power the fan) to distribute the air. Keeps the inside of a CDory 22 Cruiser very comfortable. As the exhaust is over the side, no moisture or CO. They are supposed to run on #2 diesel, but most of the CBrat crowd run Klean-heat.
