AISTER to Build the Jeune France II: A New Hybrid Aluminium Catamaran for Saint-Pierre and Miquelon

AISTER has been awarded the contract for the construction and delivery of the Jeune France II, an advanced passenger catamaran built entirely in aluminium.

This innovative naval project, valued at close to four million euros, is scheduled for delivery in September 2027. The vessel will enter service for the Territorial Collectivity of Saint-Pierre and Miquelon, replacing the current Jeune France on the strategic route between the port of Saint-Pierre and Langlade Island.

Tailor-Made Design: Direct Beach Landing Capability

The Jeune France II stands out for its technical versatility. Measuring 22.5 metres in length with a beam of 7.5 metres, this aluminium catamaran is designed to displace 75 tonnes fully loaded and accommodate up to 100 passengers.

Due to the lack of port infrastructure on Langlade Island, AISTER’s design incorporates specific engineering features for safe beach landing operations:

• Optimised trim: Enables the bow to make direct and secure contact with the seabed..
• Integrated logistics: Equipped with a hydraulic bow ramp to facilitate passenger disembarkation and the transport of vehicles weighing up to 3.5 tonnes.

Hybrid Propulsion: Commitment to Sustainable Development

In line with AISTER’s commitment to the energy transition, the vessel’s design prioritises the reduction of carbon emissions. The key feature is its parallel hybrid propulsion system, combining:

• Latest-generation diesel engines: Two 368 kW units compliant with the strict IMO Tier III low-emission regulations.
• Electric propulsion system: Allows silent, zero-emission port manoeuvres and low-speed navigation.

This configuration will enable the catamaran to achieve a service speed of 12 knots, balancing operational efficiency with respect for the marine ecosystem.

Excellence from the Vigo Estuary

The entire construction and outfitting process will be carried out at AISTER’s facilities in Moaña. With this new milestone, the shipyard further strengthens its position as an international benchmark in aluminium shipbuilding, delivering technological solutions that define the future of professional marine transport.

Key Insight: The Jeune France II is not only a step forward in passenger transport, but also a clear example of how aluminium shipbuilding offers greater lightness, durability and energy efficiency compared with traditional steel construction.
