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

The fortunately few times I've been in such a situation, my boat's been either hove to or hanging from a sea anchor, and I've been down below inventing new curse words after I'd used up the ones I...

... or an improperly secured battery. I've seen the results of that when crewing. Think "loose cannon." I've also heard of engines dropping off their mounts.

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

If the observatory is in the mouth of an active volcano, we'd better warn all those scientists who haven't noticed!

In all seriousness, the scientists thought this out:...

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

Great idea! Ingenious! One could even run the duct all the way to the bilge to catch dribbles and install a side vent low on the duct close to to the sole to achieve a sort of double-dorade effect.

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

Completely inverted and turtled: yes. Knocked down on its side with the dorade submerged: no.

One could assert a cup is water-tight when carefully inverted in water. But turn it 90 degrees on its...

You make a good point.

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

I can tolerate farts. It's becoming stupid from CO2 that concerns me.

I have an issue with one sentence from above: "CO2 concentrations in outdoor air typically range from 300 to 500 ppm." There...

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

Follow up: After a month of having a CO2 monitor on board my 26 foot sloop: the CO2 reading when I enter the cabin is 440 PPM, which is very close to the CO2 concentration measured in Hawaii...

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

Great idea... as long as you don't think about it. The balls will float in the open position if the boat is inverted or heeled past 90 degrees - gravity being what it is.

This is a really old...

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

As a pilot who flew skydivers to 12,500 feet several times a day in an unpressurized airplane, I became very familiar with hypoxia. The insidious thing about hypoxia is - the symptoms are actually...

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

I'm reporting on a scientific paper. Not suppositions. Of course, I can't vouch for the quality of the research - I wasn't there. And, like every research paper ever written, the report ends by...

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

They admit water when the vents are submerged and the vessel heels past about 90 degrees. These were storm conditions where a knock down or temporary inversion (roll/partial roll) was a possibility....

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

I've twice found myself sealed up tight down below with other crew. All hatches closed, dorades plugged, all vents sealed; to prevent water ingress from a knockdown or roll.

I noticed people...
