We met an interesting and inventive guy on our trip through the Panama Canal
who dealt with this by making his own electric hookah -- take one Jabsco
diaphragm bilge pump, attach hose and a SCUBA mouthpiece and presto, you
have cheap device that will work down a few feet. You want a diaphragm bilge
pump, not a pressure water pump, because the former is relatively high
volume, low pressure.

We used a "real" hookah from Brownie for work on the boat. Vast overkill.

For Fintry, I'm thinking about using a commercial oil-less compressor
(Porter Cable, for example) which will run air tools and, through a filter
(same filters we use on our tank-fill compressor) drive a low pressure hose
for use down to ten feet or so.

Hi,

Whenever I need to work on my prop, etc. underwater, I've just slapped
on the mask and fins and held my breath. But I've always wondered: why not
rig up a hose arrangement to be able to breathe? We're not talking 50-ft
depths here, so I'd think it would be pretty safe. Perhaps some kind of
non-collapsable hose on the end of a snorkel?

Does anyone do this? Why or why not?
