Dutch yachtmaker Heesen Yachts B.V. revealed on Tuesday that it will soon be marketing a new motor yacht featuring a hull made entirely of aluminium alloy.
Dubbing the offering 5000 Aluminium Class: Project Aquamarine, the vessel features an all-new hull design developed by the firm in conjunction with leading hydrodynamicists at Van Oossanen Naval Architects.
Per the firm, Van Oossanen conducted computational fluid dynamics (CFD) and refined the hull’s shape prior to building a 1:16 scale model for testing in the United Kingdom. The final hull design yielded an efficiency gain of 12 percent according to Heesen, accomplished by raising the transom and adding additional propeller tunnels. Such improvements translate into a draft of 2.15 meters (7.05′), enabling the yacht to navigate safely in shallow waters around the world.
In addition to improved fluid dynamics, the ship offers improved emissions. The hull’s design allows for installation of MTU’s new 16V4000M65L green oceanic engines, which feature a Selective Catalytic Reduction that reduces NOx emissions. As a result, the 5000 Aluminium Class will enter the market as its first fast-cruising yacht below 500 gross tons to be IMO Tier III compliant.
Frank Laupman of Omega Architects said in a release that the all-aluminium hull helps bring together a myriad of technological innovations aboard the ship.
“The design we created for the new 5000 Aluminium Class combines our own heritage with that of Heesen as a builder of elegant and sporty aluminium motor yachts. The ‘integrated hull and body design’, which was first seen on the iconic 65m Galactica Star, gives a strong character to the yacht’s profile.”
At present the first unit, YN 18950 Aquamarine, is under construction at the firm’s facility in Oss. Heesen projects the ship’s first available delivery date to be in January, 2021.
