??? about breathing under a boat
 
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...?

Could be dangerous. Why not take a scuba course and buy a small
tank/regulator. That way you'll be more comfortable and have a new sport to
enjoy.

You'll find that so much as a foot under water, you'll not be able to breath
through a hose...

You could do a hookah rig like a brownie, or one of the more expensive rigs,
but if you're going to do that, you might as well get diving gear and enjoy
the sport away from the boat.

"And then again, when you sit at the helm of your little ship on a
clear night, and gaze at the countless stars overhead, and realize
that you are quite alone on a great, wide sea, it is apt to occur to
you that in the general scheme of things you are merely an
insignificant speck on the surface of the ocean; and are not nearly
so important or as self-sufficient as you thought you were. Which is
an exceedingly wholesome thought, and one that may effect a
permanent change in your deportment that will be greatly appreciated
by your friends." - James S. Pitkin

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.

You can get an oilless compressor NOTE OILLESS and 50-60 ft of air
breathing hose and a regular scuba regulator. You need about 100 psi
to run a low pressure - mouth regulator. A friend just did this with a
small 120 vac compressor - it is just a little too small and it gets
hard to breath down at the 6' bottom of his keel. The comp was about
$100, the mouth reg will be maybe $100+ - look for all this stuff on
eBay.

I have a 50' hose that I use on my regular scuba tank, hi pressure and
lo pressure regulators - the extension hose goes between the hi press
reg on the tank and the lo pres regulator in the mouth.

Biggest issue for any of these is getting the connections to work -
threads - sizes, etc. Make sure that they all fit together before you
buy anything.

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.

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.

100 PSI isn't enough. The intermediate pressure in a typical SCUBA
system is set at 140-160 PSI.

Have you actually been UNDER the boat yet? Most houseboats
are pontoon boats, and you get under them no problem and still
breathe. I had to do that once (twice actually) to fix a freshwater
plumbing problem on a rental houseboat. New boat, the factory
hadn't tightened the hose clamps.

How long can you hold your breath? :)

Ok, I'm not suggesting to clean the bottom this way but seriously
though, If I'm not in a position to haul the boat and the shaft zinc
needs to be changed, I change it by just holding my breath for a little
bit at a time. It takes a few trips though. To make the trips faster I
tie a loop in the end of a rope and the first trip down is looping it
over the prop. The other end is either tied to the dock or a stanchion.
So I can pull myself up and down with the rope quickly.

Then I take the zinc down and put a screw in by hand. That takes a
trip. Then the other screw, another trip. Then tighten one then the
other, two more trips. Then I take a hammer down and pound the contacts
in, another trip. Then 2 more trips to tighten the screws again. Then
one last trip to unloop the rope.

So it takes maybe 10 trips down to do the whole thing and each trip is
like 6 or 7 feet long (around 4 feet over and 4 feet down). But it's
not as bad as it sounds. One word of advice though, keep a good knife
handy.

One time I was changing the zinc and the loop of thin line I used to
keep the allen wrench from dropping (I tie a loop around my wrist and
let the allen key hang from that so it's not in the way in transit and I
don't drop it when fumbling to get it in the screw) got snagged on
something. I think it wrapped around the shaft or prop, I don't
remember. Well, when it was time to come up for air I couldn't get it
untangled. So I just grabbed the knife and sliced the line and came up.
I lost the allen key but that's better than the alternative.:) From
then on I just use thin monofilament or thread or something that's
easily snapped in case I have to. But I still carry the knife just in
case.

Steve
