Some time ago I read about a gadget that blocked a hole in the hull. I read about it on the Net and now cannot find it. The gadget was deployed from inside the boat with an umbrella like bit, that you opened and then got pushed back onto the hull. The pressure of the water then holds the thing against the hull and reduces the flow

Anyone any idea what I am on about?

Thanks

I suspect the company Subrella is no more. I can't believe they sold many of them.

Ideas like that sound great in theory, but the chances are that any hole would be under a tank, right next to the keel, or in some other totally inaccessable place where the device would be impossible to deploy.
 
More info

Looks like they are still going, but not sure how old this info is. worth a phone call

Not surprising. The notion that a hole will be at least 3" wide but no more than 12" long and accessible from inside is laughable. Most major leaks will be splits, too narrow to get the thing through and probably too long to be covered by it.
 
Quite,
I met an American who hit something in the Carib. After collecting himself he realised that there was a bad leak and tried to find it. The floorboards floated up and he got his foot stuck under some framing. Got free, couldn't find the leak and was in his dinghy in under 10 mins from impact. Doubt if a 'brella would have helped there. Up side was, the fishing boat that picked him up was from Coasta Rica and he met a delightful girl from there who was with him when we talked.

The adverts for this wonderful "gadget" where forever in the YM,somebody somewhere must have one,or maybe they are not here to tell the takle of how they could nt get the dam thing to work!

I was in contact with Mr. Subrella a few years ago re. advertising - he told me he was retiring and he seemed to have no great plans for or interest in the continuation of the company.

The problem to me always seemed to be locating the hole in time.

Hi tudorsailor...... seems you may have to keep your finger in the dyke a little longer!

Was the enquiry because you have a problem or fear you may have one in the future?
 
Kollision Kit

This lot sell a 2-part epoxy that cures underwater. praps some remember their stand at sibs with the gear that plugged a running tap? That stuff. I bought a litre of A and B, use on its or you can bodge it onto some material etc, and cures slow enuf to have a go on the outside of the hull.

Webby's idea of finding the hole in Time is obviously better but as he says, it's difficult to locate the Stargate, although they usually seem to turn up about every twenty minutes, just after the start and just before then end....
 
Tristan Jones claimed to have invented a similar device,it was a sheet of canvas which you somehow deployed on the outside of the hull over the hole and the inrush of water sealed the hole with the canvas and then you somehow tied it in place and went on your way,(to the bottom more like).

Isn't it called fothering a sail?
 
A few years ago I read of a steel yacht bouncing off a reef and starting a leak. Not big enough to be dangerous, but needed regular pumping. Fellow yachty handed over some of his magic mix. IIRR sheep fat and portland cement. They mixed it up, went swimming, and stopped it. Later in a port for repairs, they had to chisel it off as it was so well attached.

The epoxy might be a better option for similar leaks.
