The importance of a "damage control cone"

[XDC]

From Gosport and Fareham Inshore Rescue Service (GAFIRS) Facebook page.

"The first of 2 incidents on Wednesday saw the crews paged to a vessel with engine failure, taking on water outside Portsmouth Harbour. The skipper had put out a Mayday call, asking for immediate assistance and our crews raced to the scene with a salvage pump to try and save the vessel from sinking. Once on scene with a rib from the Hampshire Police Marine Support Unit and the MOD, our crew quickly established that the prop shaft had parted from its coupling, allowing water to enter through the stern tubing. A damage control cone was inserted into the tubing (seen in the picture), stopping the flow of water and our salvage pump managed to extract the approximate 2ft of water that had accumulated inside the vessel. The Yacht was then towed into Portsmouth Harbour and lifted out of the water to prevent further ingress and allow repairs to take place. A great job by the crew in preventing the loss of the Yacht!"

A "damage control cone " is a posh version of a bung, then ?

I got a lot of crap from a couple of employers (last UK one noticeably not), for ordering bungs for the safety kit.

Not quite right think will find they launched a conical life support module .

A vari-orifice environmental situational control device surely? I shall not refer to them as wooden bungs any more.

A friend of mine in the Caribbean, used a beer bottle when a boat he was on had a similar problem. His wife could not understand why he was yelling for a “Red Stripe” when he had his head buried in the engine compartment. His previous request had been for her to get their passports and valuables into a bag ready to abandon ship. The shaft had slipped out of the coupling. They safely got into Granada.

Neat fit! In fact, a rather neat installation all around... which, together with what looks like one of those collars used to slip a lip seal on to the shaft (hanging above the water lock) makes me wonder if it was a recent installation too? Perhaps forgot to torque the bolts up?

Haven’t you missed out “Ecologically sustainable bio-degradable “?

I use my leak suppression cloths to dry the dishes sometimes.

Amazing things!

I don't have any cones but I do have a bag of conical frustra - will those do instead

Don't forget to also take a roll of extendable flexible fibre-reinforced self-binding fracture-amelioration substrate

I have a saildrive, or two.

We lost power years ago when on flotilla and hoping to make the floating bridge opening at Levkas. Initially thought the change in engine sound was something wrapped round the prop so tried in reverse. Actually that wound the shaft out of the loose coupling by changing the direction of force. Called up the lead crew and they told us not to lose the shaft because they did not have a spare! And didn't mention the hole in the boat that would leave... In fact I think the rudder was in the way. Who wants twin rudders?

I've read somewhere a suggestion to put a jubilee clip around the shaft between the coupling and the stern gland, so that the shaft won't slide out entirely if it separates from the coupling.

Yup, always done that on my own boats. If room, two with tightening screws on opposite side for balance.

You only have to see a shaft fall out once.....?

Oh and don't forget yer carrot and yer potato!

I have a large plastic cable tie on mine which I’m pretty sure would be enough to stop the shaft disappearing.

As in "I gave Boris a damage control cone and the next day I had a contract to supply PPE to the NHS?"

I have a rudder immediately behind the prop. That shaft ain't going nowhere.

I have it on good authority that lifeboats don't go to sea without an industrial size roll of J-cloths.
