I'd like to clean the bottom of my boat, while it's

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...?
Cheap and dirty way; Borrow or possibly you own a non-oil lubricated air
pump (teflon). Set air pressure at about 10 lbs and tape or clamp hose to a
snorkel that has a blowout reed near the mouthpiece.
Caution! the blowout reed is important to insure you don't embolism your
lungs.
Caution! never use oil lubricated air pump to breathe from.
