A true bluewater motor yacht

This 50-metre steel-hulled, displacement yacht combines timeless elegance with the refinement and speed to travel the globe and explore new horizons.
Blending practicality with luxurious detail, the design has been optimised to deliver the largest possible volume while still remaining under the 500GT threshold. At 50 metres this is a true bluewater motor yacht, featuring a displacement steel hull designed by Heesen’s in-house team of naval architects and engineers. Its cutting-edge design features a bulbous bow, which allows her to glide through the water with ease. Two MTU 8V4000 M63 engines provide a top speed of 15 knots. She boasts a range of 3,800 nautical miles at a cruising speed of 13 knots.

Built upon Heesen’s proven technical platform, Clifford Denn has imagined a sophisticated exterior design that is paired with generous outdoor deck space. A 98-square-metre sun deck complete with Jacuzzi, al fresco dining area and sun loungers promise the best of the yachting lifestyle. For entertaining, guests are welcomed to the 74-square-metre aft deck, an area complemented by the part-enclosed sky lounge.

First impressions

Working closely with Heesen, Clifford Denn took elements of inspiration from classic automotive design. Her traditional peak bow with reversed sheer line is seamlessly incorporated into her profile, while a militarystyle wheelhouse offers a touch of masculinity. The end result offers timeless appeal.

Step aboard

At Heesen, we aim to create an interior that truly makes a yacht a home. Therefore the interior by Reymond Langton Design boasts comfortable yet elegant spaces throughout. Its contemporary design is characterised by clean lines and surfaces. The studio selected a warm, neutral palette which is tastefully punctuated with vibrant bursts of colour from bespoke works of art and furnishings.
