The Stralsund Shipyard Pioneer Yachts is unveiling its first model, the PY60. The 18-metre-long catamaran relies on solar energy as its main source of propulsion. Founder Mike Frank developed the concept after identifying a gap in the market for practical solar-electric yachts. The company employs a team with over 275 years’ combined experience in yacht building.
Integrated energy system
The PY60 operates using an integrated energy system. Solar panels on the deck, flybridge and exterior surfaces generate electricity for the propulsion system and all on-board electrical loads. A battery bank with a capacity of 246 kilowatt-hours stores the energy generated. The 48-volt electrical system simplifies maintenance, as qualified electricians are available worldwide. In addition, APUs (Auxiliary Power Units) are available to supply power during longer voyages or when there is little sunlight. According to the manufacturer, in sunny anchorage areas, the solar panels and battery supply the on-board electrical loads without the need to use the APUs.
Performance data from test drives
Measurements taken during test voyages showed an average power requirement of 6.75 kilowatts at a speed of five knots. Pioneer Yachts states the maximum speed as eleven knots. In pure electric mode, the PY60 is said to be capable of travelling 150 nautical miles at five knots. With the APUs running continuously, the boat achieves a range of 5,000 nautical miles at the same speed. The actual figures depend on solar radiation, wind conditions and currents.
Hull design and hydrodynamics
The Italian design studio Cossutti & Ganz is responsible for the hull shape and exterior design. The sleek waterlines and optimised stern sections reduce drag. CFD analyses (Computational Fluid Dynamics, computer-aided flow simulation) assisted in the development of the keel line and the coordination between the hull and the propeller. The lightweight of 30 tonnes contributes to its efficiency. The solar panels were integrated into the deck structure and flybridge design from the outset.
Spatial design and interior fit-out
Micheletti + Partners designed the saloon. A large cockpit door connects the exterior and interior on the same level. Wide side-deck passageways make it easy to move about on board. Panoramic windows allow daylight into the cabins. The yacht is operated via central displays and throttle levers. Daily system checks are designed to be straightforward. The concept is aimed at owners who spend long periods on board and value quiet operation.
Presentation and availability
The first vessel, named Pioneer One, made its debut in Cannes from 8 to 13 September 2026. Over the coming months, the boat will remain in the Mediterranean and the Adriatic. Prospective buyers will be able to take test sailings there under real-world conditions. The shipyard has not yet announced any prices.
