Just watched the program on TV, 25 seconds for boat to sink in a lock women nearly drowned, and I didnt see what went wrong for it to sink. It floated afterwards and the program never gave you a clue either strange and very sad

It floated afterwards and the program never gave you a clue either strange and very sad Usually it's a badly replaced weed hatch that would cause a NB to sink so quickly. |

Reported as a mechanical fault which is a bit "open ended". Assuming it was the boat sunk in Fobney Lock on the K&A.

No idea boat in center of a wide lock and first picture shows it down at the stern so Martin could be right but I would have thought it would have gone under whilst on the move? who knows

Yes but normally a boat would float happily with the weedhatch off otherwise when you open the weed hatch to get shit off the prop...
It must have been a failure of something at or below the waterline. I don't think its a weedhatch unless the boat was overloaded or the welding around the bottom of the weed hatch broke off.
are there any investigations carried out into this sort of thing? I like reading MAIB reports as they are educational but I don't think there is an inland waterways equivalent unless there are casualties.

No, if the weed hatch is not replaced correctly and then you pt the boat under power (as if going into a lock) the seal will be breached, depending on how poorly sealed it is will determine how quickly the boat is overwhelmed. Once the top of the weed hatch reaches the surface of the water the outcome is then inevitable. Somebody on CWDF sank his boat in exactly the same way. I doubt there is a MAIB report as no body died or was seriously injured as you say. |

I suppose if the weedhatch lid was actually off then the act of filling the lock could force water into the engine bay quite fast.
It is noticeable how the point at which the film footage is started is at the end of a lock filling cycle. Perhaps someone simply removed the weed hatch thinking that in a lock would be a convenient moment then when water started to come in they were unable to get the lid back on.
I'm sure the facts have been established .

If it's the one I recall, it was the weed hatch, and it had been missing/not replaced properly for quite a few miles but the problems only occurred when the boat was put into reverse, which threw water upwards into the bilge. It's on YouTube somewhere.

Other option would be a catastrophic failure of the stern gland but would that really let water in at such a rate?? Only if the prop shaft was out of place possibly???
Superfluous given Mr Stabby's post.

I've experienced two weed hatch faults one on my own boat in 1994 (engine bay flooded) and one on a relative's boat (engine bay flooded and 4 inches of water throughout cabin). The speed at which it sank looks to me like a major weld failure of possibly a weedhatch which has not been replaced at all. Too much water getting in. |

Of course the last bit could be some air cooling vents taking in water .

It was a 1970s boat and had just had a two year fitout, pictures prior to sinking showed a lovely boat. they were an older couple so who knows how good the hull refurbishment was or whether they paid a professional, all I can say is it was refloated in the lock and it floated afterwards so Martins weed hatch rings right to me, maybe it wasnt put on right and a burst of reverse lifted it off? maybe the boat had been plated and the weed hatch hadnt been extended to give a safety margin? who knows? I wish I did though!!!
