€1M Price Drop on 40m Mengi Yay Motor Yacht Serenity II

The 40m motor yacht Serenity II has received a price reduction, with her asking price reduced to €7,350,000. Delivered in 2010 by Turkish shipyard Mengi Yay, the custom superyacht combines full-displacement cruising capability with contemporary interior styling and expansive guest accommodation across three decks.

Originally launched as Serenity, the Mengi Yay yacht features naval architecture and exterior design by Endaze Mühendislik, while the interiors were created by British studio H2 Yacht Design. Built with a steel hull and aluminium superstructure, Serenity II spans 394GT with an 8m beam and was designed to support comfortable long-range cruising.

The yacht for sale's interior was developed around a contemporary and understated aesthetic, combining warm finishes with large windows that introduce substantial natural light throughout the guest spaces. The main saloon is arranged as an open-plan social area with lounge seating and formal dining positioned within a single flowing layout, while the yacht’s 394GT internal volume allows for generous circulation throughout the interior. Neutral furnishings and clean architectural detailing reinforce the calm onboard atmosphere, with additional onboard amenities including Wi-Fi connectivity, air conditioning and a gym supporting both private cruising and extended stays onboard.

The exterior profile of the boat for sale follows classic full-displacement motor yacht proportions, with elongated deck spaces, a sharp bow profile and extensive outdoor guest areas spread across three decks. Her blue steel hull contrasts against the white aluminium superstructure, while exterior entertainment areas have been configured to maximise open-air usability with shaded aft deck dining spaces, multiple lounge areas and a deck Jacuzzi positioned for relaxation underway or at anchor. Wide walkaround side decks improve accessibility throughout the yacht.
