RE: [PSUBS-MAILIST] Working subs
Hi Marc, Wow to the Philippines and back in a split second - the internet
is amazing !
When it is flipped, like a spar buoy, you wouldn't be able to get out. It
would most likely be in that configuration in heaver seas, with limited
freeboard in the horizontal position you could easily get swamped. The
freeboard in the flipped position would be much greater.

I am very fond of the spar buoy configuration, and FLIP was my intro to
it as well. Perfect for habitats, but I admit I never thought of it in
connection with a personal submarine. Quick comments:
I'm assuming that your design will flip by shifting water ballast or
(better) a solid weight fore and aft?
Instead of an additional hatch aft, why not make that the only entrance?
The fewer hull penetrations, the better...
Best,
Marc de Piolenc
