Hessen’s handsome 46.7m blends bold design and precision.

A best seller for Hessen’s 47-meter class, My Secret proved to be a true story of success. The traditional and versatile four deck layout, together with the choice of Bannenberg and Rowell design team, demonstrated to be a winning combination.

This 47-metre yacht is full displacement with a steel hull and aluminium superstructure, ensuring an ultimate safe, smooth, and comfortable cruising experience.

At just under 500GT, she has the largest volume in her class, as well as a stunning design by Heesen Yacht Interior, that combines a high-quality, luxurious finish with distinctive bespoke pieces.

With minimal usage by her two owners, this is an impeccable vessel.

‘When someone buys into a yacht like this they want to buy into a dream, so that’s what you need to create’, says Simon Rowell of Bannenberg & Rowell Design.’ Quote Kate Hubert of Boat International.

My Secret features in-house naval architecture by Heesen, exterior design by Omega Architects and is presented to the market in exceptional condition. 

Her specially developed bulbous bow boasts anti-wave technology for a smoother path through the water. The result of this hull efficiency is a reduction in the engine power needed to achieve any given speed, enabling a lower fuel consumption.

My Secret attains a maximum speed of 15 knots and was specifically designed to create the largest possible internal volume under 500GT.



Interiors by Bannenberg and Rowell evoke the ‘gentle retro’ Californian style of the early 1960’s. My Secret has a defined and recognisable style, eclectic yet coherent and streamlined throughout, which is pleasing not only in terms of functionality but also from a more artistic perspective.

Broad schemes emerged for each deck, Palm Springs, Hollywood glamour and laid-back beach life. Finished to extraordinarily high standards, only the finest materials have been expertly selected and integrated, resulting in a striking finish that combines practicality with effortless style.

At just under 500GT, this 47-metre steel displacement yacht has the largest volume in her class. Her four deck levels include a master cabin forward on the main deck, four twin or double guest cabins on the lower deck and a foredeck lounge and sun pad for added privacy, even when the yacht is moored stern to. One of many outstanding features is the expansive 90-square meter sundeck, providing a flexible space ideal for sunbathing, relaxing and entertaining larger numbers of guests when in port.

What makes the concept so special is the combination of unprecedented flexibility combined with Heesen’s meticulous standard of construction. The result? A custom-built 47m yacht that represents the best value on the market.
