Default ??? about breathing under a boat

wrote:
I'd like to clean the bottom of my boat, while it's
in the water. Is there a fairly easy and economical
way of breathing while a few feet below the surface?
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...?


Be careful. If you breathe air that is at a pressure equal to just 6 or
so feet underwater, then hold your breath while ascending to the
surface, you can cause serious damage to your lungs due to overpressure.
