Whoopsie....

Looks to me that the stern swung in and landed on the handrail, but the
crane operator kept going down. I ran a crane on an offshore drilling rig
for a few years. I would have had two tag lines, one bow, one stern, to
prevent just such spinning. Well, not prevent spinning, but give a way to
keep the boat straight as the natural tendency of the rigging has to twist
once a load is put on it. But it has two basket rigged slings, so don't
know if the spin is caused from the cables above the spreader bars, or what.
It looks like there are no tag lines period. Should have been tag lines,
and it seems there was no communication, as a good ground pounder would have
yelled all stop when the boat first hit anything. Some signal, some radio
call, something.

I looked at it a couple of times and while you are right - tag lines
were missing which would have helped, if you look at the front sling,
the sling straps are at an angle to where they are on the hull - the
boat wasn't loaded right. And, I believe, but can't prove, that the
crane arms were too close together meaning that the crane was too
small for the boat.

I'm also a little suspicious of where the bow sling was placed - it
seemed to me to be a little farther back and I would have liked which
may have contributed to the sharp angle on the sling straps.
