My Secret - 2012

47m Steel

Power never means compromising on luxury

At just under 500GT, this 47-metre steel displacement yacht has the largest volume in her class. Her four deck levels include a sundeck of almost 90 square metres, and a foredeck lounge and sun pad for added privacy even when the yacht is moored stern to. What makes the concept so special is the combination of unprecedented flexibility combined with Heesen’ standards of construction. The result? A custom-built 47m yacht that represents the best value on the market.

First impressions

My Secret is our ninth 47 metre, steel displacement yacht. Her specially developed bulbous bow creates an anti-wave 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. Less power required means less fuel used. My Secret attains a maximum speed of 15 knots and was specifically designed to create the largest possible internal volume under 500GT.

Step aboard

Interiors by Bannenberg and Rowell evoke Californian style of the 1940s and 1950s. The finest woods, stones and metals have been expertly integrated with our trademark precision and dedication to weight reduction. The result – a striking design that effortlessly combines practicality and extravagant style. Bronze, leather and light and mid-tone wenge detailing have been used throughout the yacht, with intricate panels laid on the floors and other areas.
