Peter (in Dutch: Piet) has the daily supervision of all the work carried out.

Peter graduated at the Delft University of Technology with a M.Sc. Degree (in Dutch: Ir. Diploma) in 1970. During the final part of his study, in 1969, he joined the Netherlands Ship Model Basin (NSMB), initially working in the research department in the area of ship resistance and propulsion. In 1974 he obtained a Dr. Sc. Degree also at the Delft University of Technology, on a thesis about cavitation on ship propellers.

In 1976 Peter became involved in the research on sailing yachts and advanced marine vehicles and was later appointed head of the department at NSMB responsible for projects on sailing yachts and advanced marine vehicles. In 1980 through 1983 he carried out a significant research project for the Australian Challenge for the America's Cup, culminating in the development of the winged keel and the winning of the America's Cup by Australia in September 1983 by the 12 Metre Yacht "Australia II". In 1984 Peter became head of the newly-formed Design-Research Department, responsible for all design-related ship research work.

In 1989, Peter was invited to become chief designer and Technical Director of the Royal Sydney Yacht Squadron's Challenge for the America's Cup. He then left MARIN to take up this position and to set up his own yacht design office under the name "Van Oossanen & Associates" in Sydney, Australia, and in Wageningen, The Netherlands. Since 1992, he has concentrated on developing his design office in The Netherlands.
Perry van Oossanen Perry has been with us since january of 2002. He started with his thesis covering the feasibility of a Concept Exploration Model for sailing yachts and presented a paper on the same subject at the 2003 RINA Modern Yacht conference.

Since then, Perry has developed himself as an all-round naval architect with a special focus on hydrodynamics and performance prediction and optimization in the design process. He works on the development of our in-house Velocity and Performance Prediction Programs, many performance related projects and the naval architecture of various yachts and ships, ranging from small open day boats up to fast mega yachts and military patrol craft.
Geert verheij Geert joined our staff in December 2003, as naval architect. After graduating from the naval architecture course at Haarlem University, he obtained a Masters degree at the University of Southampton. He joined us after having worked at De Voogt Naval Architects (the designers of Feadship) for 3 years.

Geert is involved in mainly naval architectural work, with a focus on structural design, ranging from construction plans of large yachts through keels of sailing yachts to the smaller details such as rudders and shaft brackets.

He represents the NBJA (Dutch association of yacht designers) in ISO Working Group 18, responsible for the scantlings standards for pleasure craft.

In his spare time he races in a Soling, and he has built a wooden rowing/sailing boat which he sails in Wageningen on the Rhine river, and in raids and similar events throughout the Netherlands (for some details on the design see www.noneed.nl).

Niels Moerke Niels Moerke joined our staff full time in March 2006 and is specializing in the field of hydrodynamics and the application of Computational Fluid Dynamics (CFD) to the performance analysis of ships and sailing yachts. In addition to this he also has an interest in designing sailing and motor yachts up to about 20 m.

In the spring of 2002, he spent 3 months with us, as part of his studies at Haarlem Academy of Technology. He again joined us, in 2003, for the purpose of carrying out his B.Eng. thesis work which covered the subject of foil-assist. He then decided to continue his studies at Delft University of Technology and carried out his M.Sc. thesis on the development of the VOA patented Hull Vane concept, which included significant CFD analysis. From 2002 up till 2006, during his study, he worked with us at a part time basis.

Niels has a personal interest on Dutch traditional sailing vessels such as the Lemsteraak and Skűtsje classes. He is sailing these type of ships whenever time allows.

Niels is also active as president of the foundation “Addis Nigat” (New sunrise). This foundation is a Dutch-Ethiopian organization. They have started a primary school in Addis Ababa. The local community near the school is participating in the project. Their way of helping the people of Ethiopia is one of the millennium goals: ensuring all boys and girls to complete a full course of primary schooling. For more information, see www.addisnigat.com or feel free to contact Niels personally.

Juryk Henrichs Juryk joined our office in July 2008. He is a mechanical engineer and graduated with a masters degree in Computational Engineering. During his thesis he specialised in numerical methods. Juryk strengthens our CFD group.

During his Masters course Juryk worked with Judel/Vrolijk & Co for the 2008/2009 edition of the Volvo Ocean Race. His Masters thesis was a result of this work in which he investigated the VO70 hull form using two different codes.

Sebastiaan Zaaijer In September 2008 Sebastiaan started working with us, on the aft-ship optimization project. This work will be the basis for his M.Sc. thesis in Marine Technology at Delft University of Technology. During his masters program, he spent a year at the University of Southampton. There he followed extra modules to expand his knowledge further on (sailing) yachts, CFD, optimization and turbulence (modelling).
