Heesen Yachts delivers fully custom 50m superyacht Sibelle to her owner

24 March 2015

Heesen Yachts has delivered the fully custom 50 metre superyacht Sibelle to her owner, following successful sea trials in the North Sea.

Heesen launched the 50 metre custom superyacht in February with Boat International publishing the first photos of her after her launch. Heesen YN 16750 was built for an experienced owner who was very hands-on in the conception and build of the all-aluminium yacht.

Sibelle was launched at the Dutch yard's facility in Oss, The Netherlands, and sea trials took place in the North Sea on 13 and 17 February in waves ranging between a half and one metres high and a fresh to strong wind of Force 4 to 5. The yacht exceeded the contractual speed and proved to be extremely manoeuvrable and very quiet, according to the builder.

Perry van Oossanen, Sibelle's naval architect, says, “ the first of a kind. A Fast Displacement Hull Form with a radical styling that includes a vertical stem and very strict requirements from the owner, has really pushed the boundaries in yacht design. To see all this come together so beautifully after five years of hard work of designing and building, is a great feeling.”

The build captain of Sibelle says, “We are very pleased by the behaviour of Sibelle at sea. The speed trials – conducted without the use of stabilizers – took place in slightly uncomfortable seas with waves ranging from half to one metre, hitting us on the beam. The vessel proved to be stable and extremely manoeuvrable. The most remarkable feature is her frugal fuel consumption: at top speed (19 knots on the GPS) she uses 600 litres an hour, and at cruising speed (15.1 knots) it is only 220 litres an hour.”

The yacht is powered by twin 1,00kW MTU 8V 4000 M63 engines. Exterior lines are by Frank Laupman from Omega architects, assisted in the design details by Mikhail Labazov and Andrei Savin from Architectural Bureau A-B Studio. Heesen signed the contract for this new 50m explorer superyacht back in 2011.
