I doubt it was CO poisoning, fumes and particulates have been clearly documented to produce those symptoms too.
If suspected, then foolish not to augment with fresh air. Which would help with CO poisoning but not from fumes and particulates if irritating.
The lack of finding ANY evidence seems to confirm the consensus that a reasonably well working diesel would not cause CO poisoning in normal boat usage. All your sources mentioned are not diesel engines are are often attributed to CO poisoning. If diesels were such a danger, there would be plenty of internet evidence.
How about some, even minimal proof, of what appears to be another boating myth or one so close to myth that you have a greater chance of death by metetorite.
Find decent proof and I will retract everything and acknowledge the problem.
I'm not sure why you have such a confrontational attitude. I have no need to prove anything, but am merely sharing information. There is no ego attachment nor do I have a dog in this fight.
The statement that diesel combustion does not create carbon monoxide is not only false, it's ludicrous and potentially harmful. Burning hydrocarbons other than in a theoretical state of complete combustion
MUST create carbon monoxide. It's high school chemistry.
Now, as to whether or not people actually do experience significant exposure to carbon monoxide on diesel-powered vessels is an entirely separate issue. Yes, the nature of compression ignition internal combustion engines means higher rates of combustion; the ABYC is clear about risk assigned to gasoline versus diesel engines. Both my diesel engine and my diesel range are properly installed and in good working order, and the CO monitor sits in silent vigil. If I had a diesel forced-air furnace it would be the same case. Hell, if I had twin Crusaders burning high-test gasoline it would be the same, too.
Until something breaks.
It is foolish to believe and irresponsible to suggest to others that there is no carbon monoxide being generated by the burning of diesel. And if you truly think that there's absolutely no risk of that gas ever sneaking out, by all means omit the detector. Omit your bilge pump, too, since it's almost 100% guaranteed that your boat will never suffer emergency flooding. Almost.
As to the exposure that my captain, crew and passengers suffered, you have no idea what was happening, so why on earth would you suggest that you know what DIDN'T happen to us?
As I say, I have no ego fragility about this stuff...it's basic science and working with victims of hazardous gas exposures has been part of my professional life for decades. But if you feel that you must have the last word, please, go right ahead....
Over and out.
