Sustainability is a highly valued concern at Nautor Swan, and Swan Arrow reflects this with its innovative design. The hull is conceived to offer fine performance with a sustainable approach in terms of fuel consumption. One of the main innovations is the hybrid variable-speed marine generator developed by Mase Generators, a recent addition to their product portfolio. The yacht also features an opening platform that creates a beach area of about 50 square meters, elevated above the water thanks to the use of side openings, creating a real terrace on the sea.

The Flexi System by Mase Generators focuses on a hybrid variable-speed marine generator, combined with a modular lithium battery pack, designed to operate in two modes:

• Traditional endothermic mode, with the engine on.
• Zero-emission mode, enabling the lithium batteries to power the inverter installed inside the generator, which in turn feeds the onboard hotel services, such as air conditioning.

The system installed on the soon-to-be-launched Swan Arrow has a total output of approximately 62 kW/h, comprised of six batteries and their related Power Distribution Unit (PDU), each equipped with fuses and safety switches. The system is controlled by a BMS master and slave logic, aimed at preventing any conditions that could jeopardize the integrity of the batteries.

Additionally, the system is complemented by a liquid cooling system (glycol) and an emergency flooding system for added safety.

The entire Flexi System, currently undergoing Rina certification, will be controlled and monitored directly from the bridge through the boat’s original plotters.
