I wonder what the crane operator said as his crane went in.
Oh dear I seem to have dropped my crane.
When I saw the first photo I thought the scene looked a bit Irish the Dublin reg confirmed it.

First problem was the first crane driver wasnt parked parralell witht the key this may have prevented the original slide. See how quick some of the people in the first shot when it starts to go over get out the way and then come back to look when its all over and done with.
Only be a contender for the Darwin awards I think if the guy snuffed it.

Oooooo Dom......back to school with you....!
Problem is the first crane truck doesnt have side spreaders....or if it does it hasnt deployed them. As it is, its marginally better off NOT being parallel to the quayside if you do the geometry but the slight angle wasnt going to save it.
Whats intrigueing is that it got the car that far above the water before it toppled. By then the load should have been getting lighter as any water inside the car drained out.
Look at the second crane and you can see the side spreaders deployed.

If you look even more carefully Tony, you will see that when the car is first lifted out of the water, the boom is well below the horizontal. The front of the car is right hardup against the wall and most of the water is already out.
As the lift continues the driver comes up on the shoulder ram increasing the radius and over it goes because the weight has moved a couple of feet further outboard. If he had come down on the elbow at the same time as coming up on the shoulder he would have maintained the original radius and it would not have gone over.
Even better would have been to slew along the wall a bit and bring the car paralell to the wall, this would have allowed him to further reduce the radius and the turning moment before lifting it completely clear of the water.
We use hyrdaulic cranes everyday and once you have been taught the geometry changes, as the driver should have been, the solution becomes fairly obvious, and as you said it should have been allowed to completely drain before lifting it clear of the water.
