Van Oossanen shares its legacy

WAGENINGEN _ Van Oossanen Naval Architects, sharing 4 decades of knowledge in fluid dynamics and naval architecture, has put online papers and publications its engineers and scientists have written and presented to date.

The Van Oossanen Academy shows the company’s achievements in commercial and yachting sectors. The company says a prime objective is “to share and disseminate” its knowledge, especially as to how its concepts and designs have been developed. Over the past 25 years, Van Oossanen architects have touched on that in lectures, university courses and scientific symposium papers.

Visitors to the site will see details of “The Science of Sailing,” the book written by founder Peter van Oossanen. Some parts of the book are available as separate publications that may be ordered.

Peter van Oossanen is a titan of Dutch naval architecture. He rose to prominence as the inventor of the winged keel (left) of Australia II, winner of the 1983 America’s Cup.

Now a common feature, that keel shape unleashed a revolution. It cut resistance by 30% and offered more stability as the extra low-positioned lead in the wings created a low center of gravity. The wings were canted down 20 degrees to generate proper lift when sailing to windward.

Now led by Managing Directors Perry van Oossanen (yes, the son of) and Niels Moerke, the naval architecture studio has in the past 20 years won 2 key patents: for the fuel-saving Fast Displacement Hull Form and the Hull Vane, an underwater spoiler that creates lift and extends a yacht’s range by 20%.

A major Van Oossanen client is Heesen Yachts, the Dutch maker of fast aluminum superyachts. In recent years, a dozen Heesens have been equipped with FDHF hulls. Van Oossanen markets the Hull Vane for both yachts _ starting at under 20m _ and commercial vessels.

The studio says it invests significantly in R&D, assisted by interns or graduate students. Recent projects focused on a sail-assisted, 80m cargo vessel and a Hull Vane for both a container vessel and a new high-speed vessel concept.
