Jetten Shipyard builds New Aft Cabin Yacht concept with Hull Vane®

|

A new concept is born for owners that favour the aft cabin yachts, with the recent newbuild of the Jetten 65 by Jetten Shipyard. This new yacht design, featuring a Cor D. Rover design, focuses on the maximum sailing comfort featuring Van Oossanen’s Fast Displacement Hull and a Hull Vane®.

The Jetten 65 can be seen as the new ‘aft cabin yacht’, a type of yacht not only perfect for the inland and coast waters, the West-European and Mediterranean owner, but also perfect for the open sea, fitting the Scandinavian and the new American owner.  The design of Cor D. Rover gives this concept a brand new future, providing maximum comfort onboard for the owners by her open living space, a highly comfortable VIP cabin in the front and in the aft the owner’s cab with panorama view.

Maximum performance and comfort is guaranteed by Van Oossanen’s patented Fast Displacement Hull Form (FDHF), allowing the yacht, featuring two 550 HP Cummins engines, to reach 20 knots – giving her owners the best fuel efficiency and sailing comfort. Being responsible for the complete naval architecture, Van Oossanen also delivered the engineering and the cutting files package of this full aluminium yacht, of which the building process has started in June.

To maximise the onboard comfort whilst sailing, a patented Hull Vane® is added to the design, following the explicit preferences of the investor Paul Klaassen, who is a big fan of foils and bringing new technology to boating. He already started with improving sailing 20 years ago:

Back in 1996, I put a large foil and two small ones on my 64 foot. It had a very positive effect as it lifted the boat 18 inches, from 38 inch draft, and increased top speed by about 30% from 30 to 40 knots. Problem was the builder never built more of them and closed.  As they said about Edmund Burke: he was usually right, but right too early!”

Apart from 10% fuel savings at the yacht’s cruising speed, the Hull Vane® also reduces the pitch motions of the yacht, making her a real explorer companion for yacht owners looking for the highest levels of onboard comfort. To indicate the benefits of applying Hull Vane®, Van Oossanen simulated the yacht design in the maximum wave conditions typically encountered on the Dutch inland waters, with the help of computational fluid dynamics. This resulted in over 7% less heave motions, 13% less pitching, over 10% less vertical accelerations of the aft deck, and an overall reduction of resistance of almost 11%.

With the build started in June 2016, the Jetten 65 is scheduled to be presented at Boat Dusseldorf in February 2017. Follow us to stay updated on the progress of the building process.
