The lock is full length, 72 ft, as is all the Rochdale, so boat not too long but needs care and attention. My first thoughts were that button caught under cill too.

At around 45 seconds into the video clip from the link in post #1 there are a lot of fresh looking marks down the corner stones of the gate recess. The marks stop, in a small group, just below the lower corner of the deep upper stone which juts out proud of the brickwork immediately below it.
It looks to me as if the boat was held back hard to the bottom gate in stern gear whilst the lock was filling, causing it to lay diagonally in the chamber, and it rose with the water level in the chamber until the cabin gunwhale got wedged under the protruding stone, . . then bobble, bobble, . . through maybe a hull opening (vent), or over the top of the counter in through the door, or perhaps even a loose weedhatch top.

Surely if it was that slow everyone would have had time to get off the boat.

I was going to say it must be a full size lock. We took a 69ft boat though and didn't sink it.

I don't know how this can happen. I would have thought there would be enough time to spot that the boat was hanging up and drop the paddle before things got to this stage? My memory of that lock is that you have to use the bridge below the lock to get from one side to the other.

My memory of that lock is that you have to use the bridge below the lock to get from one side to the other. Possibly. I only ever open one paddle when I'm single handing until the lock is 3/4 full just in case I need to do an emergency shutdown. But someone said there were 9 people on the boat so there ought to have been one at each paddle I'd have thought.

True and scary.
What I don't fully understand is why people would choose to use a canal boat but have no idea how to do it or what to look out for.
It's amazing they would have got anywhere.
I suspect people DO generally know what to do but maybe got chatting to someone and failed to prioritise the handling of the boat above the social intercourse.

Looks a little long for the lock methinks? whatever their day has been ruined and 9 people in the boat might be judged as excessive? Where did you see the info about 9 people Peter ?

I suppose it could be being used as some type of trip or hotel boat and the others aboard weren't too au fait with lock operation. But equally the weed hatch may have been insecure, we've seen boats sink because of that before, particularly when running in reverse gear.

It will also have been the first lock they've done for days, it's the first on the Rochdale, leaving the Bridgewater at Castlefield.

Weed hatches are indeed a problem but it's not going to happen all that fast. I suppose if one loses situational awareness then the actual timescale is not that important.

One YouTube channel I enjoy is "TheFlightCnannel" which recreates and analyses aeroplane crashes and although some occur because of mechanical issues, a large proportion happen when highly trained and experienced pilots lose situational awareness and do the complete opposite to that which the situation requires, turning minor issues into accidents which kill both themselves and numerous passengers.

Or maybe the boat hit unexploded ordnance and was holed badly below the waterline..
All these idiots with big magnets disturbing the canal bed.
