ZEMBRA 152’ (46.3m) Delta Marine Expedition Superyacht Enters the Sales Market

Northrop & Johnson is pleased to announce the listing of ZEMBRA, the 2026 152’ (46.3m) Delta Marine expedition yacht, represented by yacht broker Wes Sanford. Asking $69,000,000, the yacht is scheduled for delivery in late October 2026.

Designed for transoceanic cruising, ZEMBRA offers 498 GT of volume and an Arizona Bronze hull, with extensive infrastructure dedicated to aviation, subsea exploration and remote-shore operations. Her bridge deck aft incorporates dedicated storage and crane equipment for a two-seat ICON A5 amphibious aircraft, while a three-person U-Boat Worx submarine is supported by specialized handling systems. An onboard scientific wet lab and 300-meter-capable Boxfish ROV further extend her exploration capabilities.

ZEMBRA is also configured to operate with a custom 55’ JR Marine catamaran shadow vessel, designed to launch and recover the four-ton submarine. Its equipment includes an integrated A-frame, hydraulic beaching bow ramp, commercial dive compressors, parasailing winch, personal watercraft storage and solar integration. Both ZEMBRA and the catamaran feature certified touch-and-go helipads. The aircraft, submarine, shadow vessel, and Boxfish ROV are available for purchase separately.

Inside, Roger Thomas, Woogmaster Studio and Delta Design Group have created an interior featuring custom cerused oak, polished stainless-steel accents, Quintus furnishings, Rocky Mountain Hardware and Tai Ping silk-and-wool carpets. Accommodations are arranged for 12 guests in five staterooms, including a full-beam main-deck master with panoramic floor-to-ceiling windows and a fitness center convertible into a sixth stateroom. ADA-compliant features include an elevator connecting all decks, wide passageways and flush thresholds throughout.

The yacht’s exterior amenities include a sundeck Jacuzzi, custom wet bar, alfresco dining, elevated bow observation platform and inflatable FunAir crow’s nest. Her onboard equipment includes four cranes, a Williams DieselJet 625 tender, Jet Skis, kayaks, paddleboards and a modular inflatable dock system.

ZEMBRA’s twin 1,200 bhp Caterpillar C32 engines deliver a 12-knot cruising speed and 15.5-knot maximum speed. Her technical equipment includes Quantum QC-1800 Zero Speed stabilizers, twin 99 kW Kohler generators and dual FCI watermakers.
