9.5 m Limousine Tender almost complete

|

The 9.5 m Limousine Tender will be delivered to the client at the end of March. The technical sea-trails were a success. Van Oossanen Naval Architects is responsible for the naval architecture and Computational Fluid Dynamics (CFD) analyses of this custom tender. The hull shape has been designed to sail comfortably at 40 knots and in choppy seas.

This tender will serve as a transport yacht to assist guests from her 75 m mother ship. The tender has space for 10 guests.

 

To view her maiden trip please see: http://youtu.be/tgznv2TYGvk

Van Oossanen selected for Concept Basin project

|

Van Oossanen Naval Architects has been granted € 40.000 to participate in the MARIN Concept Basin project. Out of 20 participants, Van Oossanen Naval Architects were chosen along with 5 other mid-size companies. We will use the budget to perform two weeks of tank testing on our new Hull Vane with Foil Assist concept aimed at lowering the overall resistance, increasing the sea-keeping characteristics and improve the overall comfort on board. The aim is to improve the performance of both commercial vessels and yachts.

Contribution year-book Scheepsbouwkundig Gezelschap “William Froude”

|

The Scheepsbouwkundig Gezelschap “William Froude” has compiled a year-book named: “Het roer om”.

Piet van Oossanen, founder of Van Oossanen Naval Architects, contributed to this fine year book by writing an article about the development of the Hull Vane™ (in Dutch).

 

The Scheepsbouwkundig Gezelschap “William Froude” is the studen association of Naval Architecture and Marine Engineering at the Delft University of Technology. The association was founded on the 17th of November 1903 and has been involved in monitoring and improving the quality of the education. Next to this, organizing excursions, guest lectures, social activities and other means to support its members in their academic career has been an important part of its existence. The S.G. “William Froude” offers its members the opportunity to discover the many aspects, possibilities and developments of the maritime industry in the Netherlands and abroad.

ARROW460 Granturismo almost in production

|

A design of Silver Arrows Marine, in conjunction with Mercedes-Benz Style

 

The ARROW460 Grantusismo from Silver Arrows Marine is almost in production. Van Oossanen Naval Architects is respossible for the naval architecture and the Computational Fluid Dynamics (CFD) of this boat.

As the order books open, Silver Arrows Marine can confirm the highly contemporary new yacht’s price tag. ARROW460-Granturismo yacht tender will launch initially with an exclusive, limited-edition fully equiped version called Edition 1 which will cost €1.25 million plus VAT, with the first yachts delivered to customers in 2015.

Fulfilling the Silver Arrows Marine dream to build a yacht that blends the best from the automotive and marine worlds, ARROW460-Granturismo yacht tender boats the unmistakable dynamism and elegance of a top-ofthe-range Mercedes-Benz car.

For the first time, Silver Arrows Marine can confirm details of the hull and the power system following months of prototype testing in a development program that has had more in common with the automobile than marine industry. Remaining faithful to Silver Arrows Marine’s aim, the yacht achieves high performance but without compromising comfort.

ARROW460-Granturismo superyacht tender will be powered by two diesel engines developing 353 kW (480hp) each. Cruising speed is around 28 knots with a top speed in light seas of around 40 knots. Performance of the special planing hull developed for ARROW460-Granturismo has been optimized using Computational Fluid Dynamics (CFD)  by Van Oossanen Naval Architects to achieve not just high speeds but all-round comfort along with the highest standards of seaworthiness.

The hull features deep-V lines in the forward part for good handling, three intermediate spray rails to deflect the water as much as possible and special propeller tunnels to allow for a conventional shaftline configuration.
