Ann G - 2015

50 metre Custom

Heesen DNA

Ann G full-displacement steel hull was designed by our in-house team of naval architects and engineers, to reach a top speed of 15 knots.

First impressions

The appointed Clifford Denn to draw the exterior profile of his unique Heesen – a perfect example of a vessel that exudes the strong individuality of her owner while keeping the family feeling that characterises all yachts delivered by Heesen. Clifford Denn interpreted the client’s brief for a yacht with a powerful and aggressive personality, incorporating complex and extremely refined design elements into the exterior lines that have been beautifully and perfectly crafted by Heesen in house expert aluminium welders.

Step aboard

The interior design by Reymond Langton is characterised by rich Macassar ebony, accented with stainless steel features to exude a luxurious, refined atmosphere with bespoke fabrics by Fay Brixton, semi-precious stones, intricate inlays and warming touches of backlit white onyx and soft tactile leather. A striking first impression for those stepping on board is created by the bespoke Art Deco-style chandelier extending over two decks that is framed by the open-tread stairs.
