gas box

[niall_m]

We're currently updating our gas installation.
Our problem is that the one ideal space for the
cylinder, under the cockpit quarter-deck (this
is on a wooden boat, btw), is very tight, so that
any self-draining box is going to be a very tight
squeeze. Can someone tell me what the thinnest possible
material is from which we could get a box constructed
to squeeze in? Any alternative ideas would be
welcomed...
(and can anyone recommend a good marine
gas engineer on the Isle of Wight?)
Cheers
Niall

I am currently pondering the same problem. As I understand, the regulations and hence insurance requirements will change next year. In the USA, they have had a requirement for years that both boats, RVs, and caravans have the gas stored outside, so that any leaks by default vent to atmosphere, bearing in mind that both propane and butane are heavier than air. I am thinking of having a stainless basket made up which will be attached to the pushpit, with a flexible pipe connecting to a bulkhead fitting with tap, so that the whole thing is isolated from the regulator, and from the internal pipework which will be 8mm copper. Again no chance of making an internal locker which must be bottom vented to allow for the heavier than air gas to escape. Anybody got any other ideas?

Hi, not had much to do with gas on boats but have had it fitted to a mobile home, the only problem i have come up against is it freezes in the cold weather and stops working if the bottles are outside.

I've seen these installations on canal boats. They're certainly effective and the probelm with gas freezing isn't an issue using propane in the UK, but a few wet weeks and the bottles often start looking very scruffy. I can't imagine that being sprayed regularly with salty water does the regulators any good either. Perhaps a small suitably sized box with drain holes may be better.

Cylinders are more space-effective than boxes. Make a cylindrical glassfibre container (use a bucket or a something similar - maybe the cylinder itself with a thin covering - as a mould) - give it a flange then screw/epoxy it to the underside of the deck. Mould a fitting to take the drain pipe in the bottom of it and mould a through fitting to take the gas pipe into the side near the top. Use a circular hatch with gastight rubber seal to access it. Voila.

Pretty much exactly what we are pondering doing on our K30...over in Dell Quay the other assorted K30s are all scratching their heads. I think one idea was to use the anchor locker in some way, but that's not an avenue we're going down. Pushpit seems the most likely option for us, methinks.

gas-tight seal is not strictly necessary ? Water-tight - yes.

As long as gas can escape via the over-board ....... gas is heavier than air. IF the cylinder should rupture and vent - then the gas pressure build up would lift any gas seal on a lid .... unless its a substantial affair ... which the average gas locker is not anyway.

Butane gas vs Propane

Butane is not tolerant of temp below 0 C

Propane will be quite happy in all wniters etc. you will experience.

There are also Butane / Propane mixes to gain advantage of butane with near propane temp tolerance.

Common practice - domestic - in Baltic.

Propane ballons are clamped into steel straps fitted into wooden box bolted to side of house. The box is made up of walls that have bottom few cms. missing to allow gas to vent out safely.

Occasionally you see metal box's but they tend to get scruffy quicker !!

The pipe-work is exterior and accessible for all work - entering the house immediately at point where needed ....... via a hole in wall.

Simple and not over-taxing ..... but above all else is safe.

Derivative of this is easy for a boat ??

I built a box which sits on the foredeck against the cabin coaming. Its just big enough to hold two camping gaz bottles which is more than enough to last a season.
Building a proper gas locker draining overboard just wasn't an option on my boat, which is also a woody, as the cocpit is not self-draining. If water finds its way into the bilges, then so will gas.

That is what I have done in the past - you can get the circular hatches from your local Chandlery - Bomar I think is the make but I believe you can get cheaper Italian/Taiwan made alternatives. I suspended mine from the deck / cockpit seat.

I'm assuming that as you mention IoW then your boat's not going inland, but please treat the information at http://www.boatsafetyscheme.com/site/part7lpginstallations_97.asp as good advice. This is the Chapter in the BSS Essential Guide that contains our regs and guidance in regard to LPG storage and supply.

Hope it helps

Another source of 'localish' advice might be Peter Spreadborough at the Calormarine Shop at Soton.
