Mr. Buddy Heater

I was going to say what ssobol did: CO is slightly lighter than air, and behaves pretty "neutrally." (Propane does sink, so maybe that's what you were thinking of.) So I have my CO detector at about head height when sleeping, or maybe a touch higher. Not at the overhead or the sole.
 
Ssobol, You are right, sorry, I mixed up CO and CO2, but I was not comparing it to air, but Oxygen. Sorry. I remember when deciding where to place my CO detector, I decided it should be close to head level while I was sleeping.

CARBON MONOXIDE HAS NEARLY THE DENSITY OF AIR. CO is slightly lighter. You can figure this out. For example:

O=16 C=12 N=14 H=2

You would add things to get the pure density of gasses.

H2 = 1+1 = 2 (very light)
O2 = 16+16 = 32 (slightly heavy)
N2 = 14+14 = 28 (about neutral)
CO2 = 12+16+16 = 44 (heavy)
CO = 12+16 = 28 (about neutral)
H2O = 1+1+16 = 18 (light) - as in humidity or steam
Radon = 222 (very heavy)

So what is the density of air? The air we breathe is composed of 80% Nitrogen, 19% Oxygen, .6% inert gases and .4% Carbon Dioxide.

N2 + O2 + CO2 = ?
.8( 28 ) + .196(32) + .004(44) = 28.9 (by definition air is neutral)

And Sunbeam, You too. Don't think I was thinking of propane, although knowing it is heavy and highly combustible, I prefer not to have it on the boat.

Earlier I purchased the Mr. Buddy MH4B to use in my C-Dory. However, I only used it once as I didn't care for the extra condensation and it was too hard to control the heat. (Either off or on are the only choices.) Since I haven't used it now in a few years, if anyone wants it, it comes with it's own carrying bag, for $50 I'll even provide the shipping. This unit is not for use in Massachusetts (must be some different laws there???). This is the Amazon link for it:

p.s. does not come with the propane tank.
