Carbon Monoxide Detectors
Any recommendation on CO detectors for a Catamaran with Generator? One for each Cabin (x 4) is my plan.

Re: Carbon Monoxide Detectors
Ours are from Safe-T-Alert (MTI). FWIW, they told me the sensor is the same in both Marine and RV versions, just different labeling on the fascia.

Re: Carbon Monoxide Detectors
I have the same ones as Chris.. However I think 4 is overkill. We have 2, one in each hull.

Re: Carbon Monoxide Detectors
Carbon monoxide is just slightly less dense than air - and with convection as it is an emission, I would install it above your expected source - no need for multiple in each cabin or hull, install it at the source.

Re: Carbon Monoxide Detectors
The thought for 1 in each cabin is that engines aft and generator forward. Assuming at night, doors to cabins likely to beclouded for privacy.
I am surprised that all charter boats (Or even all boats) do not have these installed standard .

Re: Carbon Monoxide Detectors
I have a Fireboy Xintex in each cabin and main saloon. I've had no problems with them. I agree all boats should have them!

Re: Carbon Monoxide Detectors
Along this same subject... PLEASE, install a smoke/heat detector as well. It should be separate from the Carbon Monoxide detectors. I can't believe that boats don't have them from the factory. After watching a catamaran catch fire, burn and sink in 20 minutes I promptly installed a smoke detector.

Re: Carbon Monoxide Detectors
We have a CO alarm in each of our three staterooms. It is not just your systems that can kill you but boats moored upwind can and have filled boats with CO.

Re: Carbon Monoxide Detectors
What is the need for a "marine" vs a battery operated CO detector? They will not be in the water.. Not expecting them to last more than a couple years due to environment.

Re: Carbon Monoxide Detectors
Why install a CO detector?
Deisel engines are not a source of Carbon Monoxide, are they? Just gas/petrol engines.
I have a smoke dectector, battery operated. Just a normal $20 one from the hardware store.
Boats that have propane heaters in winter may want a CO detector.

You are one of the lucky ones. The Fireboys have a habit of alarming in the middle of the night when all engines and other CO sources are shut down.

Re: Carbon Monoxide Detectors
I had a standard household CO detector but it would go off due to high humidity. I've had no problems since installing the Fireboy Xintex units.
I believe it's a myth that diesel's don't produce CO...

Re: Carbon Monoxide Detectors
ANY incomplete burning causes CO, from diesel to galley stove. So, 1. Smoke/fire products, 2. CO, and 3. Propane. No reason not to use house types. Propane low near source, smoke several places, CO anywhere people or CO accumulates. A smoke detector in my engine room was my first warning that an alternator belt was slipping.

Mark,
Diesel engines generate much less CO than petrol but not zero. Also, CO can enter your boat from a petrol boat just upwind. A CO detector is a cheap investment and would be wise for any sleeping area.
I also agree that machinery spaces and living spaces should have smoke detectors.

Re: Carbon Monoxide Detectors
Yes, diesels produce CO... although less than gasoline/petrol engines.
I guess -- but don't know -- maybe wired-in detectors are recommended because that way owners can't forget to change individual detector batteries periodically.
FWIW, some CO detectors will apparently alarm from battery off-gassing, too.
