A snorkle won't work because I'll be going under
a houseboat, but am wondering if a hose could
be made to work, or maybe a larger piece of tubing
with a hose attached so it's small enough to be held
in your mouth. Or something...?

At just a few inches under water the pressure would make breathing through a
long snorkel difficult. At a foot or more it would become impossible. Even
if you had the strength to inhale against the pressure you would be
re-breathing the air in the hose which wouldn't supply you with fresh air.

I strongly discourage any form of compressed air, either from a tank or
surface air compressor, unless you have been trained in basic SCUBA. When
you get right down to the basics, the top 15 feet is the most dangerous,
followed by depths of 100 feet or more. Without the proper training you can
kill yourself working close to the surface of the water.
