GT-40 H and GT-55 H from Imaginocean Yacht Design are two hybrid megayachts, which measure 131 feet (40 meters) and 180 feet (55 meters), respectively. The hybrid propulsion system should permit the GT-40 H and GT-55 H to top out at 20 knots, according to Imaginocean Yacht Design. When run solely on battery power, the megayachts should still make 8 knots.
Each of those two megayachts features folding balconies and bulwarks, plus a split-level saloon and main-deck masters.
