I was deeply concerned about seeing our latest RAN LHD hull arrive on a barge!
- but it appears that it does actually float. At least, it does, until they get all the superstructure welded into place - and then, it will probably turn turtle!!
I'm reminded of a certain Italian shipbuilder, around 1907, who launched a new ship down the slipway with great fanfare. The hull slid into the water with a splash - and promptly turned turtle, to their eternal embarrassment!!
