Online CFD ship analysis premiered by Van Oossanen


Van Oossanen now premieres an online service for ship hull analysis. This online tool enables naval architects, ship owners, yards and students to analyse the performance of a ship’s hull with high quality validated software, and receive a detailed test report by e-mail within a day.  This development is an important step in the development and appliance of ship simulation software.

Computational Fluid Dynamics
Van Oossanen is a leader and innovator within naval architecture, and a specialist in Computational Fluid Dynamics (CFD) analysis for ship performance. CFD is most easily described as a virtual towing tank. With state-of-the-art hardware and software, the flow around the ship is simulated in detail. Compared to towing tank tests CFD is just as accurate and often more cost effective, especially in the early design stages. In addition, CFD provides an almost unlimited amount of data flow details.

Van Oossanen’s goals are to offer easy access to their high quality optimised and validated software, as well as to stimulate awareness on hull efficiency within the maritime field. Managing director Niels Moerke, comments: “We understand the necessity to have available tools to analyse hull designs in the early stagse of a project. CFD is a very powerful but complicated and expensive tool, and with our webshop we make these simulations available for a very broad audience. As an ongoing process, we continually validate, tune and develop the CFD code to guarantee exceptionally high quality and trustworthy results.”

To kick-off the webshop, Van Oossanen has activated the option to ‘run’ a single surface bare hull via The company aims to enable the online analysis of multi-surface geometries, and to open the opportunity to add appendages and regular wave simulations as well.

Investing over 20 per cent of their time in Research and Development, Van Oossanen began working on the online ship analysis tool back in 2015. The tool was introduced to the Netherlands maritime market at the end of 2016, and has now premiered worldwide via

Online hull analysis
A key benefit is the easy-access mode; all the user requires is basic ship data and a geometry that can be uploaded at any location and at any time, the high quality validated software, and the limited delivery time of a 3D report. A history of reports can be privately and securely stored in iCloud, which makes this type of service safe and protected.

At this moment in time, the system is only capable of bare hull analysis, however, further types of ship analysis compatible with the online service are in the development stage.

BS2 became Dutch Champion for the fourth time in a row!


Our 2011 Lemsteraak design BS2 became Dutch Champion for the fourth time in a row. The Dutch Championship was divided over three days with changing wind conditions ranging from medium winds on Friday, light wind condition on Saturday and heavy wind conditions on Sunday.

With a 2 – 1 – 1 – 1 – 1 score over all the races the BS2 proved to be the best performing Lemsteraak in her class.

The design of the BS2 took a year using all state of the art design tools such as CFD and our in-house VPP to optimize the sailing performance under all conditions. The BS2 was built in 2012 by the Workumer yacht service who still has the full responsibility for the maintenance of the yacht. Last year we designed new dagger boards which further improved the up wind sailing performance of the yacht.

We congratulate and thank the owner and his team for the superb performance. A true winners team!


Jetten 45 Beach tested and to Cannes



On August 20th we attended the endurance tests on the new Jetten 45 Beach. The new Jetten 45 Beach features a FDHF hull. With her 2 x 300 HP engines she sails easily 22 knots, with a comfortable cruising speed of 17 knots. Fuel consumption at 17 knots was 70 to 80 liters depending on the sea state.


The tests took place at the Waddenzee sailing from Harlingen to Vlieland and back. We encountered wind Beaufort 6 during our travel, and the yacht took the sea state very well.


Jetten Shipyards quoted: “The cooperation with the Van Oossanen team was pleasant, peer, professional, committed and in time from design to delivery. Their predictions about the performance of the yacht were exact. The yacht is really sailing great with your FDHF hull! Very satisfied.”


We welcome the Jetten 45 Beach to our FDHF family and with her 45 feet she is the smallest yacht up to date featuring our patented Fast Displacement Hull Form.

The Jetten 45 Beach will be present at the Cannes Yachting Festival from 6-11 September, you are welcome to come and visit her.

Jetten Shipyard builds New Aft Cabin Yacht 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 maximize 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%.

The build started in June 2016, follow us to stay updated on the progress of the building process.

New 16.5 m Lemsteraak delivered to her owner


On June 9th, a new 16.5M Lemsteraak was delivered to her happy owners who asked for a re-shaped interior space and optimized sailing performance. Already being built several years ago – not to a Van Oossanen concept-, the hull did not meet the new owner’s wishes for standing height, optimal sailing performance and ultra-silent cruising.

Van Oossanen was involved in the project to meet this client’s wishes, with The Workumer Yacht Service being assigned to finish off with a very high quality standard. We improved the construction, increasing the standing height with more than 10 cm and developed a new sailing plan, with optimized appendages including the rudder and leeboards.

A hybrid propulsion was applied to allow the yacht to sail on electrical power for several hours. Due to an excellent sound isolation, the diesel engine runs very quiet. This Silent Sailing on engines allows the new owners to experience the Dutch Inland waters at its best!
