ARROW460 Granturismo almost in production

6 January 2014 | oossanen

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.
