I didn't want to further hijack the [url="http://www.catalina-capri-25s.org/forum/topic.asp?TOPIC_ID=24442"]butane heater thread[/url], so I thought I'd start this one on CO. I'm hardly an expert so I've been reading about it on the web. [url="http://www.homesafe.com/coalert/detect.htm"]This article[/url] seems to sum up the causes, effects and concerns fairly well. I haven't found a good boat related article yet, have you?

There are numerous articles in "boating" mags and such about the dangers of gensets, the "station wagon effect" for boats with canvas enclosures, and letting children swim and play around swim platforms on the transoms of boats. Here's one of several from BoatUS:

http://www.boatus.com/boattech/FumeCOdetectors.htm

Note the comment at the end about marine vs. home CO detectors. I don't know what the "calibration difference" is...

BTW, I was the one who started that "hijack"--I think the subject is totally appropriate in any discussion of carbon-based fuel heaters inside boat cabins. It's possible--just <i>possible</i>--that Chris hadn't thought of that issue. Better than waking up dead.

But it's an important topic on its own.

It seems like I need to make a correction to what I said - according to the article on CO detectors, the gas is neutrally buoyant in air and neither rises or sinks. When heated however it tends to rise, so the CO detector may be better placed in a higher location than down near the floor.
The advice on placing one on each floor of your home is sensible.

Which is why I suggest placing the CO/Smoke Detector amidships or near your primary sleeping area at about midway...

When in operation, the convective currents will mix the CO in quite evenly as it is very close to the same weight as normal air.

I see this often when traipsing through homes while on CO calls. Just follow (as best you can on a boat) the manufacturers recommendations.

Regards.
