What happens when a cradle fails.....

Interesting site at Plymouth Yacht Haven today. Looks like the cradle collapsed, leaving 40 tons of yacht on its side!

Something is not quite right in my eyes with that;

1)It looks like the yacht would have needed to be positioned on the hard, so close to the operational area of the crane, they would not be able to lift boats?

2)The mast is designed to take literally tons strain,not sure it would have broken once let alone twice.....

nope...nothing better to do......

Could be somebody 'borrowed' a few pieces of 4x2 to make an outboard stand?

Mind you a mast is also designed to take a distributed load - what you can't see is what it may have hit "off screen"?

Also if it bent once, a few of the stays / spreaders wouldn't be doing their designed job, thus inducing more weakness? They are remarkably bendy when the rigging isn't tight. Watch any of the dingy being rigged. Mast is well floppy until the strain is applied by the jib halliard.

Probably paying someone minimum wage to do a safety critical job! Perhaps expecting them to work way beyond the EU Working Time Directive Limits too so they were fatigued...

Looks like one of the old 72ft bt challenge yachts. That's a lot of boat to pick up again and repair!

Mine slipped in it's cradle last week whilst being hauled out for a survey. A big URRR! came from the watching crowd as the front strap slipped forward up the bow (longkeel boat!) The strap stopped where it should have been placed in the first place The boat dropped by about 4' at the front and stopped just before hitting the hard I did tell them they had the strap in the wrong position but would they li.......!!

iv seen a few masts break, they are very strong in the directions they are designed for. and the aluminium tube is actually quite weak, its all triangulation forces by the steel wire stays and spreaders that keep it up. 1 of them gos and its bye bye more often than not. and dent the aluminium and the tube is sicnificantly weakened.
