I had finished cooking on the magma grill (spoiled crew demanded warm

staying aboard. I cannot leave it on the grill cuz it is choppy and
the grill has to be stowed. After considering various options, I
decided littering was the safest one so I simply threw it overboard
and settled down to do some reading. A bit later, "Thunk, Thunk,
WTF?", I go outside and look down and there's the canister bumping on
the hull so I fished it out with the crab net.
This time, I really heave it far away and go to bed. Yeah, you
guessed right, middle of the night, "Thunk, Thunk", tide had carried
it right back to me.
Realizing I'm gonna have to get serious about this, I pull out the
tide tables and turn on a light eliciting lots of complaints from
sleeping crew but I find the tide will be running out in an hour. So,
I wait up till then and finally get rid of the canister but never did
get back to sleep waiting for the "Thunk, Thunk" again.

Why didn't you just slowly open it up down wind, let it empty, then
tie it up outside overnight?

No wind.

Seems like there would be something. None at all? All night? How about
tying a weight to it and the boat, then opening the valve... it would
sink down current of your boat, bubble along, then you could pull it
back in. I thought boaters were all about creative thinking?

Yeah, take all night to come up with a scheme to get rid of a little
propane gas...... brilliant.

Progressive "thinkers".. How much weight do you suppose it would take to
sink a half full tank? snerk...

I don't consider it boating, more like cave diving, far too risky, but
they sell hundred mile per hour boats. You would hit with four hundred
times the impact energy at 100 as you would at 5, with, say, a
sailboat. Such a boat might be badly, even fatally, damaged. Less
farfetched, I would not care to pay the possible repairs to the

If yer worried about a 16 oz canister, are you more worried about the
logs floating around out there from the rivers?- Hide quoted text -

16 oz canister??
I envisioned a 10 lb propane tank...... the kind we carried on my
buddy's Mirage 33.

That's the normal size, right? The kind people connect to their stove?
That's what I was originally thinking he had, but no, it's some tiny
container for little bbq.- Hide quoted text -

Normal home BBQ's use the 20 lb size.
You might see the smaller 10s on small tent trailers or older
sailboats.

MY god, do any of you ever see accident reports? A 16 oz propane
container has enough explosive potential to sink a large boat. You
can make quite an explosion by putting a few seconds worth of the
propane in a bag and igniting it. YES, I truly do mean the coleman
stove size canisters.
I also know from experience that a few mg of calcium carbide in water
will produce a mega explosion if the acetylene is allowed to
accumulate. Propane is almost as dangerous. Clearly none of you has
any experience with fuel air explosions. The amount of ignorance
exhibited here is astonishing and dangerous. All you have to do is
google propane boat accidents to see.

Fortunately I've never seen a propane explosion but they can be
spectacular and deadly, that's well established. Better to be safe
than sorry in any case, and leaking cannisters are no joke.

Here's a thought: Since half used cannisters are prone to leakage
after removal, why not carry a spare torch tip or two that you could
screw onto a leaking cylinder. They are inexpensive and should be
enough to seal it.

Come on. This has nothing to do with the scenario you described... a
slow leak from a 16oz container, with no ability to concentrate fumes.
You're going to tell us that propane, a heavier than air gas, is going
to run back up the current, then back up the sides of your boat.. what
3 feet off the water? Then, get below and go boom.

On which planet do you sail.. Jupiter?
