THE STORY OF CHANTIER DE L’ARSENAL

Yacht Concept had previously been involved in the adventure of rebuilding the Hermione, so it was only natural that in 2013, this dynamic led to the creation of Chantier de l’Arsenal. This company is the fruit of an alliance between Asselin and Yacht Concept, both involved in this ambitious project in Rochefort (Charente-Maritime). In its early days, the shipyard focused on developing an activity dedicated to naval construction and engineering, with particular expertise in the refit and new construction of traditional sailing and motor vessels, on the historic site of the Rochefort Arsenal.

In 2015, design work began on the very first DAY 1 Catamaran.

DAY 1 Catamarans are available as day charters: maxi-catamarans with sails or engines, mainly dedicated to coastal day trips.

These custom-built vessels combine adaptability, design and performance at a cost similar to production boats.

Between 2015 and 2024, 19 DAY 1 Catamarans have seen the light of day!

Chantier de l’Arsenal moves into a temporary building in the port of La Pallice (La Rochelle).

Initially designed to accommodate the simultaneous construction of two catamarans, the site will soon be expanded to accommodate four.

In 2022, Chantier de l’Arsenal will deliver its 10th DAY 1. A catamaran 19.50m long and 9.50m wide, capable of carrying 97 passengers.

The Greencat 52′ is an ecological, high-performance catamaran, launched in September 2023 by Chantier de l’Arsenal. Designed by architect Philippe Renaudeau for a young retired couple, she was specially built for their round-the-world trip, with lightweight, ecological and performance requirements.

Built using the innovative One Shape method, the Greencat 52′ uses environmentally-friendly materials such as recycled PET foam. Equipped with electric motors, 10 m² of solar panels and a rainwater recovery system, she’s also designed to make life easier when short-handed.

The OMNI is a spectacular musical work of art imagined and designed by French artist Patrice Moullet, and built in 2023 by Chantier de l’Arsenal. With its impressive 15-meter diameter, this monumental object combines art and music to offer a unique sensory experience. Installed in Hangzhou, China, at the heart of a residential complex, this creation marries contemporary aesthetics with an immersive sound dimension, transforming the surrounding space into a place of artistic expression and sonic interaction for residents and visitors alike.

SAILCOOP 61.01 was delivered in June 2024. She is an eco-friendly catamaran designed to provide maritime links between Concarneau and the Glénan archipelago in Brittany. Designed by VPLP and built by Chantier de l’Arsenal, it represents a step towards sustainable tourism by integrating ecological technologies and minimizing its environmental impact.

The NSO 1 and 2 shuttles, ordered by the Sables d’Olonne urban area, are “Hydrogen ready” electric boats designed by NepTech, built by Chantier de l’Arsenal, and equipped with state-of-the-art propulsion by Alternatives Energies. With a capacity of 50 passengers, they offer clean, silent maritime transport, and will eventually be able to run on hydrogen to further reduce their environmental impact.

Chantier de l’Arsenal has moved into its new Atelier One Shape, a new eco-friendly shipyard near the port of La Pallice. With a surface area of 4,000 m², it can produce 8 to 10 maxi-catamarans per year.

This eco-responsible building uses bio-sourced materials and algae-based paints to limit its carbon footprint. The positive-energy building is powered by solar panels, geothermal energy and bioclimatic design.

This investment reflects Chantier de l’Arsenal’s commitment to the environment.
