I have two. One on salon and the other in main berth. Cheap insurance.

Re: CO alarm on boats ?

It's a no-brainer: Put one in. Remember, the CO bonds to hemoglobin in the blood, preventing it from picking up oxygen. Bonds as in "does not let go". CO poisoning can effect you for days, and therefore be cumulative (a second dose could finish you off); a simple breath of fresh air helps, but your oxygen pickup (and therefore decision making, coordination, etc) is still compromised until it has been flushed from your system.

In a house it's a good idea; in an enclosed small volume like a boat, it is a no-brainer.

Re: CO alarm on boats ?

Yeah the Harbor Master wouldn't sign me off to have my boat in the marina without them. I have two, battery operated smoke / CO detector combinations. Westmarine has them for like $90 but Home Depot has them for $35. Other than the flashing light every 30 seconds when it's dark inside, I'm glad I have them.

Re: CO alarm on boats ?

I bought one rated for household use. It quit working last summer. I don't know if the heat or the humidity killed it. I'm now looking for one that's rated for marine use.(UL 1524 rated)

How do you know when it is or isn't working?

I have a Kiddie one from Home Depot. They're cheap. What's the downside to having one? No need to spend the money for a "marine grade" one. CO can come from your engine, your stove, your lantern or, the guy in the slip next to you with a genset that is malfunctioning. Our surveyor told us about a couple who died because the boat in the slip next to them was emitting CO2 from a bad Webasto heater.

Pro-tip: HEADACHE is one of the first signs of CO poisoning. Next is intoxication, at which point you may not be smart enough anymore to save yourself. If you suspect CO poisoning, ask yourself if you have a headache. If you do, get to fresh air and STAY THERE for a long time (it takes quite a while for the CO to get out of your blood).

Personally I like the ones that have a display. I've been able to see that my kerosene lantern (or some other source) was emitting a small, but not yet dangerous level of CO before getting the big BEEP BEEP.

Here is a good one:

I have one, and it is mounted low in the boat just below the level of the bunks. I also have smoke alarms mounted High. All Battery operated. Cheap insurance especialy if you have to motor for more than 24 hours.

We have a low-level CO-Experts model 2010. Pricier than home models.
