I've just returned from my longest ever solo trip. Three passages in a very rewarding week, Waterford to St Mary's, Isles of Scilly; Scilly to Dale, Milford Haven; Dale back to Dunmore East and Waterford.

First two passages were a bit wild, 2 reefs by the end on each passage, wind mainly in the right direction but a bit on an upwind slog into Milford Haven at the end. Final one across St George's Channel was slow but incredibly relaxing, ghosting along at 2kts in 10kts of wind, flat sea, moonlight. Great to get back to two top UK destinations and Real Ale!

The one 'anxious moment' was when a jubilee clip tried to destroy the whole boat. About three quarters of the way through the first passage - 140 miles, bumpy enough to make things uncomfortable - I went to make a cup of tea, filled the kettle, turned on the gas, and sparked the cooker burned alight. Imagine my surprise when, instead of an encouraging small blue circle of flame on the burner, I was confronted by a "whump" and a four foot yellow smoky flame from behind the cooker. "Christ" I thought, "I've never had a full-on fire on board the boat before, what the hell do I do now?" I don't know how long it took me to figure out the solution (obviously, turn off the gas) it may only have been 2 seconds, but my recollection is that it was all so unexpected (and I tired) that it wasn't immediately obvious what had happened, and what to do about it.

The gas pipe had, of course, been dislodged from the cooker as it was swinging around. I cleaned up the smoky soot from the panel to the side of the cooker, pushed the pipe back on and tightened up the jubilee clip, and pumped the bilge with the hand pump in case any gas had ended up there, but I don't think any had: I think all the escaped gas had burned off.

Thank goodness prior to that I had been attentive to my gas routine, i.e. I had turned off the gas tap when not using the cooker. And each time I turned in on again after that, I reached over to the back of the cooker to check that the pipe was still attached.

What fun sailing is, so full of surprises!

I would expect the hose to stay connected and not leak without a clip. The clip is added security. All my gas hoses have required a decent push to fit. Also, is your hose to short for the cooker ?

OK, I'll rise to the bait and suggest you need something better than a "jubilee clip" on your gas pipes. I'll leave it to others to quote rules and regulations, or say there aren't any!

Whatever, your installation was unsafe and you've been very lucky.

No - plenty of length. When the cooker is swinging around there is enough motion in the gas pipe to work its way loose eventually, and this process was probably going on over the last few thousand miles ...

There's always something....

Congrats on your solo round trip. Sounds like you had a grand time of it....

Sounds like hint to all of us that it is best to keep your gimbal locked except while you are making active use of it...

My length of flexible pipe behind the cooker is clipped to the panel. The length is enough so maximum swing both ways when connected cannot pull it at the saddle clip. The connector is a screwed fitting to the cooker, not a flexible pipe over a nipple with a pipe clamp.

Surely not difficult to do the same with your vessel?

Good job, clear thinking averted disaster. I’ve fitted a 12v powered solenoid valve at the bottle so I can kill the supply with the flick of a switch. I’m thinking of fitting a buzzer on the same circuit so it sounds once a minute or some such, avoids it ever being on unintentionally.

Thanks for the replies and ideas. Just on the solenoid idea, I hope the "flick of a switch" doesn't cause a spark ...

I put it down to 'one of those things' - just something that can happen when you least expect it, my little story a warning. As one of you wisely observed, "There's always something ..." No system is ever 100% safe and it's as well to be aware of the things that can happen.

And you still get a spark from the switch that activates the relay...

Just being provocative, I know gas safe switches and relays are available. The trick is to understand how to mitigate risks without spending stupid money and building in more points of failure
When I wrote "magnetically actuated" this is because I have just removed a redundant door sensor switch that is a reed relay actuated by a moving magnet on the door. So it is not a complete relay, just the reed part of a reed relay. Easily converted to a switch...

I think your mistake was sailing solo, if you’d been crewed you could have delegated the cleaning up after the event to the crew whilst you had a nap. So much stress sailing solo.
