Construction update: YN 20350 Project Jade, hull and superstructure now joined together

by Heesen Yachts 26 Aug 2022 02:48 PDT

With her engines installed and her hull and superstructure joined together on August 20th, Heesen is delighted to confirm that Project Jade's construction remains on schedule.

  • 50-metre semi-displacement, fast all-aluminium motor yacht below 500GT
  • 23 knots top speed, IMO III certified engines
  • Shallow draft - just 2.15 metres
  • Exterior by Omega, interior by Cristiano Gatto
  • 12 guests in five cabins
  • Available Spring 2024

Jade, YN 20350, is the third in the shipyard's popular 50-metre semi-displacement Series, which builds on Heesen's legacy of fast, hard-chine aluminium yachts.

Heesen launched this Series for clients whose need for speed extends to a desire to shorten the delivery time and enjoy their yacht sooner. A unique cocktail of Dutch pedigree, crisp exterior lines by Omega Architects and a rapid top speed of 23 knots makes Project Jade and her sisters extremely attractive, along with her shallow draft and excellent hydrodynamic efficiency.

"This combination of speed and shallow draft makes the design ideal for cruising in shallow coastal waters such as the Bahamas, as well as the crystal clear waters of the Mediterranean," commented Heesen's CCO, Friso Visser. "This is a compelling proposition for many yacht owners."

The high speed is achieved thanks to the streamlined lightweight aluminium hull, which boasts an efficiency gain of 12 percent compared to the previous 50-metre Satori design, coupled with two IMO III-compliant MTU 16V 4000 M65L engines. Heesen is the first shipyard to deliver fast, sub-500GT yachts that comply with the new emission regulations. Future-proofing new designs is at the heart of the shipyard's philosophy, and Jade is no exception.

Heesen pioneered the on-spec construction of Series superyachts over 20 years ago, with the introduction of the 37-metre. Other shipyards have since followed Heesen's lead, but even now none can offer fast aluminium yachts, of Northern European quality, on a shortened delivery schedule.

As a result of thorough and precise design and engineering processes, as well as perfect execution of the build, Heesen's Series yachts can be guaranteed to perform exactly as predicted, which is reassuring for both brokers and clients. But each yacht's interior will amaze everyone in its own way. No two in the Series are alike. Jade's cosy, contemporary interior design by Cristiano Gatto will be perfectly engineered and installed by the in-house interior construction team - Heesen being one of the few shipyards in the world to have its own interiors division. A team of 100 expert craftspeople based in Winterswijk deliver flawless execution of the most intricate designs.

YN 20350 Project Jade is available for delivery in Spring 2024.
