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.
