Alexis is a 384-foot, nine-deck Explorer Yacht Concept from Steve Kozloff, founder and designer of the Goliath Series of polar-class expedition yachts.

If an owner is traveling to northern latitudes, the designer says the full-displacement yacht will have an ice-class steel hull, aluminum superstructure as well heated handrails and doors to mitigate ice buildup.

Standard engines will be four 16-cylinder, Cummins QSK60-M diesel-electric powerplants for 8,000 total hp. For perspective, each engine weighs about 19,300 pounds. That’s big iron. The motors will be matched to four azipods.

Alexis is expected to cruise at 10 knots with a 14.2-knot top-end. The designer says the yacht will have globe-girdling range: 22,000 nautical miles at 10 knots. It’s a trip that requires some serious fuel and Alexis will reportedly hold 432,000 gallons or 1,728 tons of diesel.

For the owner that likes to fly, the yacht is designed with 3,000 square feet of hangar space, which the designer says should accommodate four small helicopters or three medium helicopters. Her garage can reportedly accommodate, not one, but two submarines, several tenders and other assorted water toys.

The superyacht’s design includes a master suite aft with a private pool. The pool will have a retractable cover. A second pool for guests, located on the foredeck, will also have a retractable cover.

The builder says the explorer-style superyacht will have three master suites, plus seven twin guest staterooms with accommodations for 20 guests for extended voyaging.
