Best season has started and everybody in the industry is working hard to succeed. Here are the Van Oossanen Naval Architects Team results so far.
Dynamiq Stefania has launched
Dynamiq has launched its 41-metre GTT135 after just over two years of engineering and construction. Stefania is Dynamiq’s first GTT135 – a full-aluminium motor yacht with an exclusive metallic gold and dark brown colour scheme.
She not only looks terrific, she also runs extremely efficiently and comfortably while achieving high top speeds – the culmination of yet another successful collaboration between Dynamiq and Van Oossanen Naval Architects.
She owes her low resistance to a combination of our patented Fast Displacement Hull Form (FDHF) and Hull Vane®. Her top speed exceeds 20 knots with a transatlantic range of 3,500 nautical miles.
Heesen’s 50m aluminium-class Aquamarine at sea trials
One of Heesen’s latest aluminium yachts – the 49.8m Aquamarine – has been out on sea trials. Heesen Yachts worked side by side with Van Oossanen Naval Architects’ hydrodynamics specialists to create a hull design with a 12% improved efficiency and a 2.15-metre draught, which is ideal for island-hopping and exploring shallow bays.
Aquamarine’s two MTU 16V 4000 M65L diesel engines operate with a selective catalytic reduction (SCR) to reduce emissions and create an eco-friendlier, sub-500GT, Tier III-compliant motor yacht with a top speed of 23 knots.
Alia Yachts has launched the 36m PHI Phantom
Turkish yard Alia Yachts has launched its 36-metre PHI Phantom – a shadow vessel to Royal Huisman’s 58.5-metre Project PHI, first announced at the 2019 Monaco Yacht Show.
Van Oossanen developed the concept in close collaboration with the Captain, and provided naval architectural services. Cor D. Rover Design came up with its exterior styling. The same team was responsible for the design of PHI Phantom and the 55-metre superyacht Project PHI, which is currently under construction at Royal Huisman in the Netherlands.
Sporting a Fast Displacement Hull Form (FDHF), the shadow vessel will be used for transporting toys, tenders, a small car and extra fuel for her mothership. It will also feature a large laundry and additional crew accommodation inside its 199GT interior.
Although she’s essentially a workhorse with plenty of cargo space and a crane with a lifting capacity of 15,500 kg and a reach of 11.5 m, she’s been styled to resemble her mothership. Power comes from twin Caterpillar C32 engines for a top speed exceeding 21 knots and a transatlantic range of 4,200 nautical miles at a cruising speed of 12 knots.
Two Port of Antwerp vessels launched
Kooiman Marine Group launched its latest POA2 patrol vessel in early April (POA1 was launched in March). These two aluminium patrol vessels aren’t standard, however. They had to meet particularly high standards of both safety and sustainability.
Not a problem for these two 25-metre, hybrid, aluminium vessels with a combination of Fast Displacement Hull Form (FDHF) and Hull Vane®. Faster. More efficient. Lower fuel consumption. Reduced CO2 emissions.
Van Oossanen becomes Water Revolution Foundation corporate partner
Van Oossanen Naval Architects believes wholeheartedly in contributing towards a more sustainable future. To achieve this, we’re minimizing the impact on the environment through our design work and engineering, as well as how we operate as a company. "We’ve always believed it’s been our social responsibility to do business this way. But now it’s time to do even more and show this to the rest of our industry and the world at large. This is why we’re affiliating with organisations such as Water Revolution Foundation," says Perry van Oossanen.
Van Oossanen Naval Architects currently have forty-six vessels under construction at nineteen shipyards in four countries.
Peter van Oossanen founded the company in 1992 under the name Van Oossanen & Associates but it’s now known as Van Oossanen Naval Architects BV. Perry van Oossanen joined his father in 2001 after graduating from university in Maritime Technology. In 2002, Niels Moerke joined the company as a student and worked his way up through the ranks while studying Naval Architecture and then Hydrodynamics. Together, Perry and Niels took over the helm of the company in 2012. The company specialises in the design of high-performance boats, ships and yachts, as well as many other advanced, special‑purpose marine vessels.

Luca Dini Design & Architecture has entered into an agreement with Albania’s Ministry of Infrastructure and Energy to explore the development of a national maritime strategy. The initiative aims to position Albania as a sustainable yachting hub in the Mediterranean.The proposed strategy involves creating a network of interconnected marinas designed to share resources and infrastructure rather than compete. The approach intends to improve logistical efficiency, support regional economic growth, and reduce environmental impact. Albania’s geographic position near established yachting destinations such as Greece and Montenegro, along with its undeveloped coastline, is seen as a foundation for attracting seasonal boaters and superyachts.The project envisions the development of service facilities including repair yards, refit stations, and fueling areas to meet international standards and accommodate larger vessels. The plan emphasizes adopting sustainability principles in new marina construction and diversifying specializations across different locations to reduce congestion and environmental pressure. Intermodal transport connections with road and rail networks are also part of the proposed strategy to link coastal and inland regions.The concept aligns with European Union initiatives such as the Trans-European Transport Network (TEN-T), focusing on integration with continental trade and logistics systems. Luca Dini Design & Architecture will contribute expertise in architecture, yacht design, and master planning to the project. The firm indicated that the next 15 years represent a critical period for Albania to establish itself as a competitive maritime destination through coordinated planning.Credits: Luca Dini Design & Architecture
