This is one option, but you can pick up a tank, regulator and mask cheaper.
Most YMCA offer very inexpensive diving classes so you can get certified.

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...?
