I’ve just studied all that document about Heinke hoods etc
and immersion suits and calculated the time to flood my sub with a 2”
valve but had to have a bit of a think about bubble lines and blowing etc.
A bit depressing. Thought I might start designing an aeroplane
instead. One thing though Frank, I think we need to be friendly to all
those ROV operators who could guide an anchor within grabbing
reach!! The other thing which is interesting is that they appear to
only flood the compartment to about 80% ( Bubble line ) then appear to equalize
with Air pressure or is that wrong. They have a Blow term and a vent
valve for equalization of the last part. How about something from one of
you chaps who have actually done the escape! Chs, Hugh From:

[mailto:owner-personal_submersibles@psubs.org] On Behalf Of ShellyDalg@aol.com Would it be practical to wear a wet suit ( or dry suit) when
escaping from our psubs? They are hard to put on, but would help keep you warm,
and add buoyancy when at the surface. Why don't they use scuba tanks for
escape? The article mentioned escape from 900 fsw.....OUCH! Better to stay put and have the means to grab a hook dropped by a
rescue boat. I was thinking a manipulator arm could grab a hook and attach it
to the sub, so you and the sub could be hauled up. How the hook arrived below,
within reach of the arm would need to be figured out, but escaping a downed sub
doesn't sound very good. Frank D.
