I am not challenging your integrity, nor do I doubt that you have posted support for your position somewhere here on Sailnet. However, I am not going to expend my time searching the internet for evidence supporting an assertion I believe to be incorrect. I feel the onus to prove rests with the proponent of an assertion that is contrary to established understandings and recommendations.
If you have authoritative, scientific evidence to support your position, I would honestly like to read it. And if it is convincing, I also think someone should contact the US Coast Guard and ABYC to apprise them of their mistake. At this time, both of these organizations continue to warn against the use of portable gas generators aboard recreational vessels due to the risk of CO poisoning. Both also state in their guidance regarding CO that diesel engines pose significantly less threat. The relevant portions of the ABYC document states:
"Portable Generator Sets - Do not use this equipment on boats. Gasoline powered portable generator sets produce CO. These sets discharge their exhaust products in locations which can lead to an increase in the accumulation of carbon monoxide in the occupied space."
(ABYC TH-22, Educational Information About Carbon Monoxide, July 2002, at 7); and:
"What Makes Carbon Monoxide?
"Carbon monoxide is produced anytime a material containing carbon burns, such as gasoline, natural gas, oil, propane, coal, or wood. Common sources of CO are internal combustion engines and open flame appliances such as cooking ranges, central heating plants, space heaters, water heaters, fireplaces, and charcoal grills.
"The carbon monoxide component of diesel exhaust is extremely low relative to the carbon monoxide level found in gasoline engine exhaust."
(ABYC TH-22, Educational Information About Carbon Monoxide, July 2002, at 1-2, emphasis added.)
The US Coast Guard adopts this ABYC guidance and incorporates it by reference in its safety bulletin on CO. (US Coast Guard Boating Safety Circular 74 -- Carbon Monoxide, The Invisible Killer (June 1992), Citing and Incorporating ABYC Technical Information Report T-22 (Educational Information About Carbon Monoxide), January 1992. [citing an earlier versin of the ABYC adivisory above]).
You and I have had this debate before, and I think we agreed to disagree. Which is fine. I also acknowledge that many cruisers are using portable gas gensets. I just don't want an inexperienced reader of this thread to draw the wrong conclusions for lack of sufficient information.
