[Closed] Dragons Den - would you trust your mega yatch with their invention?

I would. The way bannatyne demonstrated it not working could never happen, my limited knowledge of how pressure works tells me.

I can't see how it works......

How can you disconnect the inner pipe from the valve, open the valve to force the plastic widgit through without water pouring in?

...or is it just me??

[i]The way bannatyne demonstrated it not working could never happen, my limited knowledge of how pressure works tells me.[/i]

Yeah! Can't believe no-one picked him up on that. Water pressure from the outside would behave nothing like him pulling on the inside end of the stick. Amazing how someone so stupid can be so rich 😆

I hope they do well with it. Nice simple solution - as Piers said, it's either a crackpot idea, or the next "Cat's Eye". Bannatyne, as he was on QT the other day, is beyond ignorance sometimes. (Granted, he's managed to amass a fortune despite being an ignorant arse, can't deny that.)

^^ exactly what I was thinking whilst watching the show.

Youd have to remove the pipe and push it through whilst water is coming in. Which isn't too bad as the pressure will be low, but if it fails to seal it coud be a whole load of fun

I could see it as an emergency device as it could stop you sinking but not as a maintenance device as why risk sinking your boat ?

It [i]would[/i] work - just about, but my argument is why would you risk your boat/yatch with something so flimsy which had a potential to fail with catastrophic results

As a guess...

Have device ready
Put bucket under valve
Open valve
Push device in, collecting excess water in bucket.
Change valve
Pull device out, quickly closing valve.
Collect excess water in

Isn't its rubbery flimsyness what makes it work so well? The dragons were all flexing and pulling it in ways it wasn't designed for, but it didn't break.

I don't really see what it's mean't to achieve as a "safety" device.

For changing the ball valve, without lifting the boat out of the water then yes, i can see a use, but if a pipe fails mid ocean and water starts flooding in, then you just shut the valve. Unless of course the valve has seized shut, in which case, you need to get over the side sharpish with a cork! 😉

(or you use a pipe clamp to squeeze the pipe shut before the leak!)

Take it none of them of are sailors? YES the water will be coming in. But not for long.

You get larger similar devices for emergency hole patching. Bits of sail secured in place and scraps of ply wood and a battery gun are other techniques.

I've done it for a blocked toilet supply pipe using a bung for temporary stoppage. Bit disconcerting but probably good to practice it in case you need to it in a hurry. A seacock assembly could vibrate loose and come off. They are kept simple so you can get a bung in it. A threaded "Tap" would be a disaster.

I'm thinking that when I change the ballvalve in my Sunseeker I'm jumping overboard with a softwood bung and letting it swell in situ or freezing any paperwork with water in situ.

Worst "by the way, did i mention i have a speedboat" post ever!! 😉

Except that (arguably) the biggest hassle is separating the seacock (valve) from the through-hull fitting (the mushroom headed bit that the rubber gizmo seals against) without disturbing the latter's seal with the hull. The only way of gripping the through-hull is usually a couple of lugs inside the bore. Usual practice[* ] seems to be a mate stood outside the hull (on dry land) with something wedged against these lugs, bracing against the torque that you're applying to unscrew the seacock inside the hull so that the through-hull doesn't move.

"Standard" safety equipment for the emergency scenarios they mention has (for donkey's years) been a selection of softwood bungs and a mallet.

[*] If doing the job yourself - otherwise, just cut the through-hull out with a grinder without bothering to remove the seacock and fit a new stuff.

Is it pronounced "Throat warbler mangrove"?

So are the STW Dragons out then? (and my Mrs wrong to invest)

I am so glad someone picked them up on this.

Glad to be of service. 😉

Just found out this guy is a colleague, small world eh?

A couple of weeks ago he didn't realise that rechargeable toothbrushes had batteries in them...

The one thing that I wondered about was the likelihood of it getting adopted as required safety equipment. Can an item that only one company could supply be required equipment for all the world's vessels? I could understand if they allowed it to be manufactured by anybody and took a small percentage of all those sold but I don't think that is what they were doing as they wouldn't need investment for that.

Looks simple enough

I imagine they could if they wanted, stuff like sea water scrubbers for removing SO2 from the exhaust are licensed or sometimes patented technologies or equipment, although there's more than one company with a different way of doing it providing them.

Looks simple enough

Except that the bit at 0:50 doesn't go like that in real life...

...And a common mode of failure for those cheap'n'nasty ball valves is for the ball to sieze and for the spindle to round-off (so they can neither be opened or closed).

I'm oot.

(Also, he should have two clips on that hose.)
