With 100% hindsight, that small ship (only about 13K deadweight tonnage) ship and the way the yacht was loaded on it looks like a disaster in the making. The yacht is aligned with the centerline of the ship with its tall mast left in place. That ship in the open seas of the Atlantic and Med is going to be lively which would work the deck attachments and the cradle quite a lot over time, weakening both, especially with the added moment of that mast. Notice that the smaller vessels are stowed athwartship. This monster should have been stowed at as much of an angle as possible on a bigger ship with is mast down.
