Any idea of the price? I just tried calling the number on the website but it's unobtainable.
Replacing a seacock whilst afloat: too good to be true?

Very impressive. I'm not sure that I'm brave enough to try it though.
Why not - don't you ever clean your log paddlewheel.

Ah! the fruits of determined refusal to either use or regularly service your seacocks.
All those owners of French AWBs, have you changed your raw-water seacocks @ year 5?

No I don't have to clean it because it's ultrasonic. No moving parts, never needs cleaning.

I once had one of those, a Doppler log, no less inaccurate than a paddle-wheel type.

Never mind. £49.99 from Force 4.

A similar item is used to change the main incoming gas valve on gas supplies to buildings. Have been assured it is quite safe but still makes me twitch when I see it done!

Reminds me of when I started work at the gas board as a fitting apprentice in 1970, the fitters often had to change the main gas inlet valve (next to the meter) which was a snip, just check there were no naked flames and a bit of ventilation, unscrew the old valve and replace it quickly with a new one. But ocasionally a new fitting had to be soldered on to the old live lead main. There was a expanding tool that went through the old tap and expanded in the lead pipe but the old pipe was usually a bit battered and usually it wouldn't make a good seal.
Some used a flexible wire tool with washers fitted along it's length to stop the gas but it was not unusual for it to be leaking gas out whilst you were soldering the joint.
I was sent with a fitter to be shown how to do it and he just stuffed a strip of wet rag down the pipe and compressed it down with a screwdriver, cut off the old fitting then lit the blowlamp and soldered in a new fitting, this was common in those days, the disconnected meter if uncapped was the classed as biggest danger being potentially a bomb.
Most of these jobs were performed in the corner of a small internal meter cupboard single handed, I am sure there must have been accidents but I never heard of any.

That seems to be a routine method in France. It's in the Les Glenans Manual.

In an emergency situation it would be very useful. About 6 years ago a friend was tied along side me at the Folly, we were merrily having a few drinks on my boat when his wife popped back over to theirs. She calmly called over that there was water in the boat and as we all scrambled over we saw the water was above the saloon floor. A sea cock had snapped below the ball valve and a quick thinking member of the party dived over the side with a champagne cork which luckily fitted perfectly in to the skin fitting.
We bought a new valve from island harbour and fitted it with the cork keeping the water out. Having one of these devices wouldn't have made the job any easier but certainly having one would give you the fore thought of what you would need to do.
I'd buy a couple.

Midshipman Fother would be pleased to see it! A much larger one would also be a very good idea for emergency collision control.
Just seen the price - about £40 too much I'd say! I think I'll try making a large one!

My 1999 Bene, Ive had a good look at them all. The prop shaft water lube one had some pink on the threads of the thru hull. It had a SS hose clip on it when I bought it, the previous had earthed the engine and anode to it! I have just changed it, I had to cut thru the thread to get it out. The walls of the pink bit were still solid, it was surface discolouring only! It didnt need changing! I am confident the rest are OK

This would be good gadget for removing seacocks in good condition but those aren't the ones you want to replace. I can foresee problems like loosening the skin fittings so I wouldn't risk it.

After I left the motor trade in late '60s I went through the gas board training school and, IIRC after about 2-3 weeks there, was chucked out with a bag of tools to go and repair domestic appliances such as Ascots, cookers, fridges etc. and some ('orrible job) factory toilet st incinerators. No vans then, they gave us bus tokens to get around.
We were given tapers like long cake candles to light appliances and to check for leaks - well away from the meter of course. Bet that's no longer considered safe practice.

I get rather annoyed when recent Health and Safety legislation is derided. The introduction of the Health and Safety at work Act 1974 has transformed the construction industry so I would ask "what is wrong with protecting working people's lives?"

use padded moles elsewhere on the hull fitting thread to stop it rotating
i have changed a seacock in the water with a bung to hand, once with going over and putting a bung in, and the 2nd time without. you can always put the bung on the inside if you can't get the new valve to thread on...

Working in the Chemical manufacturing industry, we are competing against the Indians and Chinese where labour and construction coasts are lower. I would like to think that our competitors were applying the same health and safety rules as us. They aren't. I work in Hazard and Operability Study and some of the stuff we learn from our Asian collogues is scarey.
I'm not saying we need to be dangerous.
We need to have good risk assessments, not scary risk assessments, realistic risk assessments.
Goal Zero is easy, do nothing, the challenge is making stuff with acceptable risk.

I agree about risk assessments having done and reviewed hundreds of them. You have to invent risks just to fill the spaces on the form. It is never acceptable to write "there are no risks associated with this activity" even when that is true.

You should see the risk assessment for a fishing boat. What bugs me is risks are rated as 1, 2, and 3 for both likelihood and consequence, and then multiplied, so the result can only be 1, 2, 3, 4, 6, or 9. Should they not be added?
