A new joint central agency has been announced on the recently launched 46.3-metre Delta Marine expedition yacht Zembra, now listed for sale with Wes Stanford of  Northrop & Johnson and Kevin Kramer of Burgess.  

Designed for transoceanic cruising, Zembra offers 498GT of volume and an Arizona Bronze hull, with extensive infrastructure dedicated to aviation, subsea exploration and remote-shore operations. Roger Thomas, Woogmaster Studio and Delta Design Group are responsible for the interior. 

Zembra is asking $69,000,000

Accommodation is arranged for 12 across five cabins, including a full-beam main-deck master with panoramic floor-to-ceiling windows and a fitness centre convertible into a sixth cabin. The guest accommodation is positioned on the lower decks, where a gym is also included for wellness activities on board. 

ADA-compliant features include a lift connecting all decks to allow for easy access between decks for guests.

Meanwhile, the main saloon is a social hub comprised of multiple sofas, coffee tables and a dining table. Custom cerused oak, polished stainless-steel accents, Quintus furnishings, Rocky Mountain Hardware and Tai Ping silk-and-wool carpets feature throughout.

Outdoor living is encouraged on the explorer yacht, with a lounging area on the main deck aft as well as an al fresco dining area on the bridge deck aft offering a space for all guests on board to dine. 

Up top, the sundeck features a spa pool surrounded by soft furnishings for the ultimate relaxation spot, positioned forward to benefit from the uninterrupted views ahead. The deck is designed for socialising, offering a custom wet bar paired with a second al fresco dining option.

For keen explorers, an elevated bow observation platform and inflatable FunAir crow's nest provide the ultimate sea life watching spot.

Zembra is also configured to operate with a custom 55’ JR Marine catamaran shadow vessel, designed to launch and recover the four-ton submarine. Both Zembra and the catamaran feature certified touch-and-go helipads.

Zembra's twin 1,200 bhp Caterpillar C32 engines deliver a 12-knot cruising speed and 15.5-knot maximum speed on this yacht for sale. Her technical equipment includes Quantum QC-1800 Zero Speed stabilisers, twin 99 kW Kohler generators and dual FCI watermakers.

Zembra is asking $69,000,000.
