Northrop & Johnson is pleased to announce a €1,600,000 price reduction on the 138’11” (42.33m) Mondomarine SERENITY, represented for sale by Yacht Broker Deniz Kaymaz. She is now offered at €15,900,000.

Delivered in 2015, SERENITY is an award-winning semi-displacement motor yacht built by Mondomarine with a strong emphasis on volume, privacy and long-range cruising. Her innovative design was recognised at the 2016 World Superyacht Awards, where she won in the Semi-Displacement and Three-Deck Motor Yacht category over 41 meters, and she was also named a finalist at the ShowBoats Design Awards.

SERENITY’s layout is what truly sets her apart. The entire upper deck is dedicated to the owner, creating a private apartment rather than a traditional stateroom arrangement. The split-level master suite enjoys panoramic forward views, fold-down balconies to both sides and direct access to a private foredeck sunpad. Aft, a private lounge and cinema room opens onto a large terrace with dining for 10 and a dedicated bar.

The main salon is bright, elegant and highly functional, with full-height windows and fold-down balconies that create a strong connection to the sea. Forward, a formal dining area is subtly separated while maintaining an open flow throughout the space. Accommodation is completed by four well-proportioned guest suites on the lower deck, making her equally well suited to private use or charter.

Outside, SERENITY offers generous deck spaces designed for relaxed living on the water, including a sundeck with an infinity-style pool, sunpads and shaded lounging, as well as a spacious aft deck and large swim platform. Built in aluminium and powered by twin MTU 12V 2000 M94 engines, she reaches 16.5 knots and offers an impressive range of 4,500 nautical miles at 12 knots.

With her award-winning design, highly unusual owner’s deck, long-range capability and standout presence in the 40 to 45-meter market, SERENITY represents a compelling opportunity at her new asking price.
