Sort of like a giant duck bill! Wait until they start building
"stealth" destroyers (the DD21 program here in the USA)--those have
some really, really, really funky lines.

I've seen trucks that match that description--I wouldn't be surprised
if Tenix use the same sort that Bath does. Our ships of DD size and
smaller (at least) are all prefab, so we do use them.

That's because they actually (as you may already know) time the launch
to be in tune with the tides--even a tiny bit of shear can lodge the
vessel or cause it to miss its channel--or worse, damage it and its
slip severely. In Maine (Bath Iron Works) they're on a river, so
they had to compute the exact moment of null tide--which, when the
river's volume can fluctuate, is no easy task! For them, the floating
slip is well worth the trouble.
Oh, to be a naval architect...
