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

Mauna Loa and Mauna Kea are not erupting. The variations are on the order of 10 PPM, not 100 PPM. The top of a mountain in the middle of the Pacific is a pretty good place to collect air samples free...

I dunno Cpt, I think you and I, if we ever find ourselves in such a spot, won't see our ol' CCA boats stay upside down too long.

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

Very brief drift, sorry...So this comes out the linked article as an FYI. I can't find the curve for my skinny boat right now but it is a little better (or worse if you like more modern hulls) than...

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

Hence the utility of the self sealing vents?
The longest I’ve been cooped up inside on a passage was, iirc, 5 days, mostly for non-stop spray coming over the boat. Down below was muggy and wet and...

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

I am not clear why one would seal up the dorades. The amount of water that may come in is so small and manageable, it seems to be of no benefit relative to the risk of running out of oxygen and/or...
