Heesen Yachts launch YN 16750, Sibelle

Heesen Yachts have announced that project YN 16750 was launched and christened Sibelle at their shipyard in Oss.

Sibelle is a 50 metre fully custom motor yacht, below 500 Gross Tonnage with an aluminum hull and superstructure. The owner requested this project be designed with a plumb bow which will ensure the vessel stays on course better in high wave conditions.

Sibelle will be able to reach a maximum speed of 18.5 knots.

The naval architect, Perry van Oossanen said: “The hull is fitted with Quantum XT zero-speed fins, and bilge keels, offering a maximum reduction in roll angle at anchor. The design of the hull, the appendages and the propulsion arrangement have been focused on obtaining the best fuel efficiency possible, without sacrificing performance and comfort when running in waves.”

To describe the design of Sibelle the team of architects chose the oxymoron Complex simplicity, as the lines may look like they are running parallel, but in reality they do not.

Sibelle will be tested in the North Sea and delivered to her owner in March 2015.
