Tecnomar dropped.

Someone got that badly wrong, never seen all the lifting strops break like that. They were lucky it wasn't much higher.
 
looks like a sequential failure, with one strop or shackle breaking then throwing overload onto others in turn. So, either dodgy strops/shackle, sharp hull edges, or someone confusing BS with SWL. The failure of one strop should have been easily taken up by the others

Very sad for the owner, but also for the insurance who will be lumbered with consequential damages.

Yep it is a remarkable video on that score Sarabande. The 2nd from front fails, and the remaining front strop can't take the load on its own. The dropping of the bow then causes the front strop on the aft crane to take all/most of the aft load, and it breaks. Then the remaining aft strop breaks. So at both ends of the boat, one on the pair cannot hold the load alone, = a safety factor of <2. Remarkable!

Just as a guess, the boat was being unloaded having just got to its home waters (S/America) where its owner is based, after build/launch/trials/magazine reviews in Europe. The boat is somewhat famous for the very large amount of marble specced by its owner (marble floors, table tops, everywhere, etc) but while that = several tonnes it shouldn't have added enough weight to cause this and the weight of the boat as built was surely known (including from craning her on board that ship in Europe). In that vid it looks like a geared ship so you'd expect those very same 2 cranes and strops were used to load the boat onto the deck at the Europe end. Dunno for sure tho - guessing

Looks like it dropped about 10ft or so , enough to do quite a lot of damage to the boat.

We had a sizeable aluminium boat that hit a reef a few years back and the damage was surprisingly limited in spread.

Aluminium reacts very differently to GRP in so far as the impact is absorbed by the aluminium in the vicinity of the impact, so if its aluminium that can be repaired but the 10 ton or so of filler used for fairing the lines will need replacing.
 
Many years ago (80's) we were called to Southampton container port to assess the damage to a 50 something ft C-Kip which was being lifted from her quayside cradle into the water when a shackle parted and she dropped 4 ft onto the concrete. Not only did the sterngear suffer but engine and machinery mounts broke, bulkheads shattered and popped, the hull distorted, glass smashed, - the list was endless. It very quickly became clear that repair costs exceeded the insured value and the vessel was sold for scrap.
