The Thalassa's clean minimalist exterior is owed to British Malcolm McKeon Yacht Design

The Thalassa’s exterior is quite different from traditional motor yachts’ aesthetics, as she was designed by renowned British sailing yacht expert Malcolm McKeon 

A long and sleek hull, a low freeboard, a flat, uncluttered foredeck and balustrades are all elements typical of sailing, not motor boats, let alone such large ones. Malcolm McKeon is known as a designer of a number of outstanding sailing yachts (take the 59.7-metre Sarissa by Royal Huisman, for instance). Even the concept projects that have not been built yet (for example, the world’s largest 85-metre sloop, Apex 850) always make a big splash in the industry.

The owner’s determination to allow McKeown to actually "redefine the genre" along with Feadship’s skill to bring these bold ideas to life have made it possible for us to admire the vessel that is sure to win numerous design awards. 

The graphite-coloured steel hull with a vertical bow contrasts strikingly with a silver aluminium superstructure that looks weightless due to the continuous glass bulwarks and balustrades. The overall strictness of the exterior is softened by the warm teak and shiny black accent panels. The radar equipment does not violate the profile’s cleanness either: instead of bulky satellite domes there are flat Starlink receivers.

The key idea behind the Thalassa’s design is constant contact with the sea and the sky almost anywhere on board: there are huge windows, a transformable winter garden with folding glass panels, an open sundeck with a minimal hardtop and a round jacuzzi and certainly the cascading lounge area aft. This beach club of 165 sq. m (!) is the largest ever built by Feadship.

The pool with a length of 6.37 m on the main deck features a glass bottom, which lets the sunlight reach the lounge with fold-down side terraces below. It required some really innovative engineering solutions, as their closing and opening mechanisms are located within the doors themselves, and not inside the hull sections. As a result, Feadship managed to provide a 180-degree view and the terraces located just 700 mm above the sea. They expand the fitness area with a space for doing yoga, cardio and weight training and function as launching pads for water sports.

The Thalassa can accommodate 12 guests and a crew of up to 15. Her “warm and relaxing” interior is owed to Milan-based M2Atelier studio, but the details will be available later. The megayacht’s provisional top speed is up to 16 knots, but the exact characteristics will be reported later, after the sea trials that are to take place in the nearest future.

“This yacht represents a new design chapter in the Feadship story, and the look is proving popular,” said Feadship Director Jan-Bart Verkuyl. "Achieving a profile this clean whilst accommodating the technical complexity of the stern architecture and the scale of the beach club openings demanded a high level of engineering innovation. McKeon's brief challenged us in the best possible way, and the response from the market suggests we have delivered something the industry has been waiting for”.
