Re: Riding out a storm, sealed up tight down below. Watch out for CO2.

So is it correct that degraded cognitive performance/incapacitation is the main concern here? Of all the threats to cognitive performance/incapacitation on a sailboat, where do you place high CO2 in...

Re: Riding out a storm, sealed up tight down below. Watch out for CO2.

Yes. Bolded parts are the bottom line.
C02 sensor/alarm is not necessary or desirable, all things considered. I referenced the NNT/NNH metric upthread; where the proposed intervention can solve no...

Re: Riding out a storm, sealed up tight down below. Watch out for CO2.

I wish he was joking. Please consider re-reading what was said. He is articulating concern that the ambient effective partial pressure of oxygen would be depleted so as to present a safety concern....

Unicorns carrying ham sandwiches arriving on the boat is also bad. To promote the use of 'unicorn with ham sandwich proximity alarms' suggests exceptional foresight in the unicorn/ham sandwich...

Re: Riding out a storm, sealed up tight down below. Watch out for CO2.

John, you don't seem to understand basic biology nor perhaps combustion. In responding to Taipe you neglected to quote the parts where he was trying to correct you. I'm certain that on review Taipe...

Re: Riding out a storm, sealed up tight down below. Watch out for CO2.

Your point is specious and fear-mongering if not substantiated.

Which precise gases in about what total concentrations from which precise sources are you contending to potentially cause a...

Re: Riding out a storm, sealed up tight down below. Watch out for CO2.

As a practical matter, completely remove low oxygen concerns from the radar screen on a sailboat (or car/van/truck for that matter) unless you're drugged/drunk/carrying dozens of pounds of dry ice....

Re: Riding out a storm, sealed up tight down below. Watch out for CO2.

Re: Riding out a storm, sealed up tight down below. Watch out for CO2.
