Of course a good deep v could handle it. But with as much "comfort" ??
The first & last videos were "demo vids" by the mfgr I believe.That could be why no names yet.
These are lobster boat hulls designed as work platforms for the Canadian winter fishery. The demo was done in the harbour entrance. Those boats fish up to 50nm. offshore in the winter N. Atlantic.
Conditions can get much worse.
Please note-he wasn't trying to just run in or out with the seas.
He was playing in circles,stopping & lying a-hull like a work boat has to & backing down into snotty conditions that most of us pleasure boaters would not enjoy.
My point is that semi displacement hulls have improved greatly from the plodding 8 knotters of yesteryear.
As for the "Starship" foredeck shape-meh-I'm not big on it.
In my (Fundy) tidal area,it would be hung up on the wharf often.
But,it does shed the spray,without having to add "downeast" spray rails
