Congratulations are in order as Heesen Yachts launched YN 19480, Project Cosmos on November 19, 2021. As the largest and fastest all-aluminum yacht ever built, she is 80 meters long, with a gross tonnage of 1,700GT and a top speed of about 30 knots. Cosmos is the perfect example of how far Heesen is willing to go in terms of daring, complex projects.

Largest and Fastest All-Aluminum Yacht Ever Built

What makes the project Cosmos so remarkable is its large size combined with her top speed. This was achieved thanks to the lightweight and low-drag hull design that was created by Heesen’s naval architecture department on an iteration of the Fast Displacement Hull Form that was originally penned by van Oossanen, and put together by Heesen’s welders.

Sophisticated, Sporty, Strong

One of the biggest technical challenges facing the engineering team was to ensure sufficient longitudinal strength; they designed and patented the Backbone – an “intricate, full-length structural reinforcement system”. Cosmos is traditionally powered by diesel propulsion with four engines, two gearboxes, variable pitch propellers, and Promas rudders.

Cosmos’s sophisticated exterior design was penned by Winch Design, with a sporty profile and the extensive use of glass, which will of course stand the test of time.

“The Winch vision for Cosmos was to retain Heesen’s sporty DNA but blend it with an innovative, futuristic spin. Curved glass forms smooth, sculpted shapes, creating a feeling of slick, contemporary charm,” said Jim Dixon, Director of Yachts and Aviation at the British design house.

Utmost Comfort at Sea

For her interior, Sinot Yacht Architecture & Design created a “light and soothing” design to create the utmost comfort at sea. The palette is neutral with pops of blue color throughout the vessel’s insides, creating a warm environment. The centerpiece of the yacht is its large beach club, with side and stern platforms for direct access to the ocean.

Following her launch, Cosmos will stay at the Heesen yard for commissioning before undergoing sea trials in the North Sea, and will be delivered to her new owners in April 2022.
