YN20555 Project Serena - 2024

Delivery: 29 November 2024

Timeless profile

Heesen’s 55-metre steel – a uniquely successful superyacht platform. Worldbeating, fuel-efficient Fast Displacement Hull Design, ocean-crossing range, huge interior volumes and a timeless profile – and available on a short delivery schedule, thanks to Heesen’s bold speculative build programme.

Larger windows, assertive shapes, and longer horizontals lend a more aggressive edge to the profile. But take a closer look, and there’s a new French balcony in the owner’s suite. A transformative innovation.

“This is one of the most impressive innovations on the latest version of the 55-metre Steel,” says Heesen CCO Friso Visser. “This is something truly unique that fundamentally changes the space.”

Enhancements to exterior deck spaces are not limited to the upgraded furnishings. Functionality in the new-look 55-metre Steel is improved by additional stairways to provide better access and circulation for the crew. Less formal layouts for the aft seating areas complement a new focus on alfresco dining.

First impressions

The muscular exterior lines of Project Serena, have been revisited by Frank Laupman of Omega Architects. “As much as we love our original design with the vertical windows, we felt it was time to make an evolutionary step,” said Frank. “We opted for a larger expanse of floor-to-ceiling glass, without mullions, in the main saloon and sky lounge. Then we took the opportunity to give a slightly more aggressive look to the profile, by using continuous sheets of tinted glass. The horizontal lines stretch the optical length and balance the air draft. The result is beautiful: we retained the family look and feel, but gave it an elegant touch.”
