About SAILCOOP

Boat presentation

An optimized, eco-designed catamaran

Designed by the naval architecture firm VPLP and built at the Arsenal shipyard, this 18.60 m catamaran was named Isabelle, in honor of its godmother, French sailor Isabelle Autissier, famous for her solo circumnavigation of the globe.

It provides eco-friendly, carbon-neutral maritime connections between Concarneau and Les Glénan in Brittany, promoting sustainable and environmentally friendly tourism. Its main propulsion is provided by a 182 m² sail, making it a particularly eco-friendly and efficient vessel in terms of energy consumption and CO₂ emissions.

Two 79 horsepower combustion engines are also on board to supplement the propulsion system if necessary or for maneuvering in port.
Capable of accommodating 80 passengers, this catamaran is designed to be accessible to people with reduced mobility, with access ramps, adapted toilets, and interior fittings that facilitate movement.

Focus on ethics

A boat that incorporates a wide range of ecological and social considerations

  • Wind propulsion.
  • 8m2 solar panels.
  • Made entirely from recycled PET foam.
  • Excellent insulation thanks to a thick composite sandwich of up to 60mm.
  • Deck layout to allow access for people with reduced mobility, with a PRM WC on the deck and access ramps.
  • Streamlined hull design for improved hydrodynamic performance.
  • Installation of dry toilets in the hulls, reducing the catamaran’s weight and saving water.
