Northrop & Johnson is pleased to announce the 138′ 97″ (42.33m) motor yacht SERENITY is now jointly listed with Yacht Broker Deniz Kaymaz, asking €17,500,000.

Delivered in 2015 by Italian shipyard Mondomarine, SERENITY was conceived as a fully owner-driven project, with a clear emphasis on volume, privacy and long-range capability. Her innovative layout and naval architecture were recognised in 2016 when she won the prestigious World Superyacht Award for Semi-Displacement and Three-Deck Motor Yachts over 41m, along with finalist recognition at the ShowBoats Design Awards.

One of SERENITY’s defining features is her owner-focused layout. The entire upper deck is dedicated to the master suite, creating a private apartment rather than a conventional stateroom. The split-level suite offers 180-degree panoramic views, generous proportions and direct access to a private forward sunpad, with fold-down balconies on both sides. Aft on the owner’s deck, a private lounge and cinema room opens onto a spacious terrace with dining for up to ten guests and a dedicated bar.

The main deck salon is bright, open and practical, with full-height windows and fold-down balconies. Two full-size sofas face each other in the lounge area, and the dining area is subtly separated by a low central partition with an integrated fireplace, maintaining flow without closing the space off.

Guest accommodation is arranged on the lower deck, with four well-proportioned suites, each with its own colour identity and ensuite bathrooms finished with onyx basin tops.

One the exterior, SERENITY offers generous deck areas including a sundeck with an infinity-style pool, sunpads and shaded lounging, a bridge deck aft with a dining area, a relaxed main aft deck close to the water, and a large swim platform for easy sea access.

Powered by twin MTU 12V 2000 M94 engines, she reaches 16.5 knots and delivers an impressive range of 4,500 nautical miles at 12 knots.
