This craft is a prototype. Half sailboat, half ice yacht, it was especially designed to face all the challenges brought on by this project :

• The Hulls : insubmersible therefore full (Shape polysterene), resistant to shocks because they are covered with kevlar and light so reinforced with carbon.
• The center board and the rudder, retractable, can be lifted manually in case of shocks
• Habitability : Lightweight, in a polysterene kevlar sandwich, resistant, in carbon PVC foam.
• Rigging : simple yet adequate, therefore a carbon wing mast was chosen.
