YN19480 Project Cosmos



At 80.07 metres, 1,700 Gross Tons and with a top speed of 29 knots, Project Cosmos will be the world’s largest and fastest full-aluminium motoryacht with conventional propeller propulsion system. Winch Design was appointed by the owners to create a streamlined yacht with innovative design traits but still retaining the Heesen DNA: muscular sportiness and timeless elegance.

First impressions

Some of the most notable features on board Project Cosmos are the fully-rated helicopter landing pad for a Eurocopter EC135 that transforms into an outdoor cinema with stunning effect; the crystal elevator from the lower deck to the sun deck for chic accessibility; the breath-taking seven-metre pool with contra-jets for swimming, paired with a waterfall and glass bottom; the sumptuous beach club with a sunken walk-around bar and large transom and side platforms.

Step aboard

Sinot Yacht Architecture & Design created the interior design of Cosmos. Elements from nature, natural mathematics, such as the Fibonacci sequence, form the basis for the interior architecture. Together with clear graphic lines, the result is a clean architectural environment. Special, featured materials, such as backlit onyx, straw marquetry and crystal glass panels are framed within the architectural lines to emphasise the beauty of these materials.
