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.

Designed from scratch and with a completely innovative development, the prototype of the HS60 interceptor is ready to start operating in Algeciras. The vessel, designed by AISTER in their shipyard in Moaña, is designed to fight against illegal immigration, drug trafficking and organized crime, and the truth is that the sea trials carried out in Vigo showed more than satisfactory results.

Top speed and manoeuvrability are two of the boat’s strongest points. Thanks to its experience in the construction of interceptors and a detailed development of the project, AISTER has been able to exceed all expectations. With 18 meters in length and 4.5 meters in beam, the HS60 comfortably exceeds 60 knots top speed with two MAN inboard engines of 1800 hp each, powering two HamiltonJet waterjets. The prototype design is the result of a great effort in design, engineering, performance, safety and comfort.

The interceptor also guarantees a quick and agile response to situations that require a quick or unexpected manoeuvre, being able to reduce the crash-stop to about two boat lengths.

The HS60’s speed and manoeuvrability characteristics make it the first vessel of its kind in the world.

A qualitative and quantitative step forward in the evolution of high-speed interceptors

With this new model custom-designed for the Guardia Civil Maritime Service, AISTER has taken another step forward in the evolution of high-speed aluminium interceptors.

In addition to their performance in terms of speed and manoeuvrability, the HS60 has an interior and a 360° visibility exterior steering position that offers great habitability and comfort, both in the cabin and in the engine room, thanks to the high standards of thermal and acoustic insulation.

It is designed for four crew members and has ergonomic seats with anti-shock protection, as well as cabins and kitchen for longer cruises.

It was in February 2022 when the collaboration agreement between AISTER and GMV was announced, the shipyard located furthest north on the planet. A milestone that would allow us to reinforce our strategy of building eco-friendly ships. Now, one year later and after several months of intense work, the first project from this strategic partnership has been completed in the AISTER facilities in Moaña, becoming the 84th construction for our shipyard and 184th for the Norwegians.

This is the first catamaran constructed for the salmon aquaculture industry. A mooring handling vessel that will work as a tool to control and move the fish cages, as well as for mooring line maintenance.
It is a simple ship but, at the same time, with several characteristics: it has keel cooling, which are external coolers attached to the hull; it has transverse maneuvering propellers at the bow and stern; it has two propulsion engines, with shaft lines with controllable blades, what is known as variable pitch propeller, and a generator.

With a length of 15 meters and a beam of 10 meters, the NJORD catamaran also has a complex hydraulic system to supply all the hydraulic equipment, a winch, and various deck equipment, including two cranes, one with a capacity of 65 t·m and another with a capacity of 33 t·m.

The first one built in Spain with friction-welded panels

It has undoubtedly been several months of hard work for AISTER from the start of construction to the launch and completion of the project. Work that, thanks to the union between our shipyard and GMV, has been resolved by achieving a new milestone, as this is the first catamaran built in Spain using friction-stir-welded panels.

On this case the project had Norwegian design and AISTER has provided the hull fabrication, hydraulics, electrical installation, piping, painting, fitting and insulation, apart from the assembly of all interior and deck equipment.

The NJORD, heading to Norway

With construction and final equipment work completed, the NJORD was launched this week in the Vigo Bay and on Wednesday, February 8th, she was loaded onto the ship responsible for transporting it to Norway, where it will begin operating for the Mortenlaks shipowner, known for its commitment to sustainability.

Following the awarding of the contract through a public tender for the design and construction of a fisheries inspection patrol boat for the Consell Insular d’Eivissa, AISTER began the design phase last April, followed by the manufacturing of this first MZ10 model. Now, after seven months of construction, the vessel has been launched, delivered, and is already operating in Mediterranean waters.

Speed ​​and agility, strong points of the MZ range

Like the MZ12s for the Andalusian Regional Government currently under construction at the Moaña shipyard, the MZ10 stands out for its agility and top speed, characteristics that make it the perfect vessel for fisheries inspection work in coastal and port areas.

With a length of 9.4 meters and a beam of 3.1 meters, the AISTER MZ10 is equipped with two 300 HP outboard engines that allow it to exceed 45 knots. It features a polyethylene foam core cleat coated with polyurethane and excellent hydrodynamics thanks to its deep-V hull made of naval aluminum.

The vessel also stands out for its control cabin, providing almost 360° visibility, one of the most significant features of the MZ range and ensuring easy docking and maneuverability. It also features a toilet, a fully equipped console with the latest electronic equipment, and all the necessary tools for inspection work.

A modern and functional design, capable of reaching high speeds and specifically designed to perform its task, while its structure and equipment ensure reliability and comfort while sailing in all types of conditions.

After completing the construction, outfitting, and initial testing in the Vigo estuary, the MZ10 was transported to Ibiza for delivery and final on-site assessments before beginning work in Mediterranean waters.

The completion of this project marks a new milestone for AISTER, closing out a successful 2022 in which the evolution of its designs and construction once again places us at the forefront of the sector. Our adaptability, combined with the performance offered by naval aluminum construction, allows us to be open to the needs of each shipowner to meet the objectives of each project.

The contract, which was awarded through a public tender selection process, is due to expire in the summer of 2023.

AISTER has been selected by the Agricultural and Fisheries Management Agency of Andalusia for the design and construction of four fishing inspection patrol boats. The award of the contract represents a new challenge for the Galician shipyard, being these the first units of the MZ12 range to be built for fisheries inspection work.

Fast, agile and resilient

Designed for fast intervention thanks to its agility, top speed and autonomy, the MZ12 stands out as the ideal vessel for operation in coastal and harbour areas. In this case, the vessels will have a top speed of more than 40 knots thanks to its two outboard engines of 350 HP each and seats with impact mitigation, which guarantees a comfortable and safe navigation at high speeds, avoiding injuries and fatigue in the crew after hours of patrolling the high seas.

With an overall length of 11.38 metres and a beam of 3.5 metres, its deep-V hull made of naval aluminium gives it optimal hydrodynamics for its task. They will also have a GPS position-keeping system which, by means of its joystick system (joystick piloting for outboards), will ensure easy docking and manoeuvrability in all directions from the control cabin, one of the most significant elements of the MZ range thanks to its 360º vision, with a very high visibility capacity and equipped with a complete console with the most cutting-edge electronic equipment.

The structure and equipment therefore ensure reliability and easy handling in all conditions, and will include a davit system for lifting gear and nets.

Summer 2023

The four patrol boats will be built at the Moaña shipyard with a delivery deadline of summer 2023, when the first MZ12 patrol boats are expected to be launched. Once the construction and outfitting work has been completed, they will be transported to Andalusia for delivery and final in situ tests.

The culmination of this project will be a new milestone for AISTER in the evolution of MZ vessels, and specifically of the MZ12 line, as a result of the evolution of the Galician company’s designs and constructions over the last few years.

Thanks to our capacity for adaptation and the features offered by naval aluminium construction, at AISTER we are open to the specific needs of each client and we work closely with the shipowner to create a design that meets the specifications and needs of each vessel.

The two boats built in the shipyard based in the Vigo’s Bay have already been moved and delivered to France to start operating immediately.

As planned when the project was announced a year ago, AISTER has just delivered two hybrid boats in France for passenger transport in inland waters. These boats are equipped with the latest technology in hybrid propulsion, respectful with the environment and with a design covered in wood inspired by the historic barges that were used within the area of the Charante River, famous for its environment, vineyards and its tradition related to the production of cognac.

The completion of this project means another milestone for AISTER in the evolution towards an eco-friendly business line opened eleven years ago, when the shipyard from Moaña built one of the first 100% electric ships for passengers in inland waters in Spain, the named “Juan de Homar”, which currently operates in the “Canal de Castilla”.

The Department of Charente was in charge of launching a tender for both themselves and for the Community of Agglomeration of the Grand Cognac, located in the west of France. The aim was to build two twin boats that would emulate the old liquor transport barges, typical from the Charente River, to join them for tourist purposes covering tourist routes in a unique environment like the area of the Nouvelle-Aquitaine region.

The design came from a French technical office -SDI- and AISTER has been the shipyard in charge of the integral development. The boats are 20 meters in length and has capacity for 69 passengers, wi-fi connection, and all the comforts in order to cover three routes a day of approximately an hour and a half.

Hybrid propulsion, the marking point of the project developed by AISTER

It is, undoubtedly, the strong point of the project. The initial purpose was that, for a total of three journeys a day of one and a half hours each, the boats built by AISTER could make half of the route in electric mode and the other half part with the integrated diesel engine. However, the shipyard from Moaña has developed both boats so that they can cover the entire route in 100% electric mode without the need of using the equipped diesel engine, which completely eliminates environmental pollution.

As a result, a new success for the Galician company which continues adapting to evolution and with the aim of continue betting on eco-friendly technology.

After finishing their construction in the shipyard of the Vigo’s Bay, the two boats were transferred to France for delivery this week and last on-site tests.
