slopping around in there?
If you prefer to be outside, again, how do you deal with hypothermia? How do you secure yourself to a slick inverted hull in any kind of seas? How do you get potable water? How do you get food
I think there are a number of unanswered questions about remaining with a capsized cat versus getting in a raft. Maybe some of you have answers?
I think you're working from a false premise: that air trapped in the upturned hulls is the only thing keeping the boat afloat.
It's actually unlikely that the hulls would be airtight. There would be sink drains, toilets etc, that would keep water out of the boat when upright, but would not be airtight when inverted.
Boats built form modern materials float quite high inverted. A Lightwave that was pitchpoled crossing Wide bay bar floated with the bridgedeck well clear of the water. Lightwaves used to have the escape/re-entry hatch in the bridgedeck floor - and it was reportedly still useable, with sufficient airspace between the waterline and the bridgedeck floor.
So it wasn't trapped air keeping the boat floating as high as it was.
Again the story of the Rose Noelle proves inverted multi's can be habitable. The 3 crew susrvived for months, and stayed remarkably healthy.
