Overview

Super Yacht Sub 3 was designed from the keel up to live aboard a yacht: small enough for a tender garage, light enough for a single-point crane, and finished to match the rest of the vessel's interior.

A hyper-hemispherical acrylic viewport gives both passengers a near-total panoramic view, while the optional Freeboard Extender adds stability for launch and recovery in rougher water.

Six superyachts already carry a Super Yacht Sub as standard equipment — including Shinkai, the first superyacht ever designed around a submersible.
