Beyond Celebrity Apex, look!  It’s a container ship

from 1988

escorted into port by 2016 Trident.

The 2016 Trident, 99′ x 44′ and 5730 hp, has an unusual configuration below the hull:   she’s a Robert Allan Ltd-designed advanced rotortug (ART), meaning three engines and three Schottel z-drives, creating triangular propulsion to enhance maneuverability. See more on that here.

National Glory is a 575-teu box ship.  That’s NOT 15000.

In comes another, Galani, 1732 teu.  Assist is provided by a 1995 Broward, 5100 hp, 96′ x 40, a relatively conventional z-drive boat. 

The other assist is from the 1998 St. Johns, 88′ x 50′ 4000 hp and nothing conventional below the waterline.  She is referred to as a “ship-docking module,” aka SDM design.  See a schematic and read all about it here.
