I have just detected a (small) gas leak on my boat using the Alde
bubble leak detecter I installed a while ago. I have fixed the leak,
just a compression fitting on a tap needed a tweak.

It was a very small leak, just a bubble a second or so or even a bit
less. It's LPG (propane) though and is thus heavier than air and will
sink into the bilge. The leak has been there for a few days (probably
three or four days) since the gas was turned on, I only just got some
propylene glycol to replenish the bubble detector. Presumably the gas
will eventually diffuse but should I do something to clear any gas
that may still be sitting down there and, if so, what?

The boat has a diesel engine (sitting immediately above the bilges)
which sucks air in from the outside and (presumably) blows it out of
the exhaust. The engine was running for several hours yesterday and
Saturday so that would, I guess, have cleared things a bit. So the
accumulation is probably only over the last 24 hours since yesterday.

My feeling is to let sleeping dogs lie and leave it to diffuse,
there's no source of combustion down there anyway.

You need to clear it out as it will have gathered in the bilges. Get a small bucket and scoop up the air gas mixture and throw it over the side. You might think you look stupid doing it but not half as stupid if a spark sets it off

A further point. Do you not have a bilge fan ? These are spark proof so safe to use. As a precaution we always run the bilge fan for a minute or so before starting the engine. Better safe than sorry

It's something I've had in mind for a while but I don't have one yet.
It is only a small boat (10 metres or so), not the sort of boat where
bilge fans are standard.

Thanks for the other ideas folks, I'll be scooping out soon! :-)

I'd like to encourage you to do that, but April 1st is over...

If you can't smell the gas, don't worry.

The odorants are added in concentrations so that gas becomes noticeable well
before dangerous concentrations are reached.

Otherwise: remove all you clothes so as to avoid any chance of static buildup
and sparks. Take two fans, dance on the deck of the boat, while fanning air into
the bilge of the boat. Extra points for singing!

If I were worried, I would be inclined to rig up a fan to blow air into
the lower reaches of the boat to forcefully stir it up and out. It
would be wrong to put the fan in the bilge, where it might ignite the
collected gas.

More effective, would be something like a vacuum cleaner hose, which
you could drop to the bottom and suck the gas out - except for the fact
that the gas would then pass through the vacs motor. LPG leaks in boats
are a deadly combination, due to it being heavier than air.

If the OP has a compressor then using the air directed up the vacuum

Mobiles transmit even when they re not being used so it isn't because
they are transmitters or you would have to turn them off before you got
to the petrol station for them to be safe.

Some years ago we tried to upset a petrol pump and then tried to ignite
some petrol fumes around the tank filling hole on a scrap car.

No mobile phone did effect either, the only way we got a "light" was
with a 25 watt PMR radio with a mag base with the aerial tip arcing
across to the metal work of the car body on the filler hole!.

I think my Karcher (and some other tub vacuums) have separate openings for motor intake and exhaust cooling fan, and vacuum suction exhaust air.

Not sure I'd risk it though.

A lot of boats have diesel heaters, but more seriously there's nothing

And/ or waste heat from the engine, for space heating on the move - as
we found with one boat we hired, in winter. It was its only means of
heating and the nights on the water can be very cold in the winter.

No, there are very specific and well defined rules for installing and
using it in small boats in the Boat Safety Scheme.

Mostly the rules are very similar to those for using it on caravans
and camper vans (where it is very widely ised too). However there are
few differences, in particular you can't guarantee gas 'drainage' on a
boat like you can in a land vehicle.
