Not Your AWB
Thomas Heatherwick explains a boat design commission to transport tourists and locals along the Loire river between Nantes and Saint-Nazaire.
Unlike a traditional two-hulled catamaran, the boat will have a single hull that folds back on itself and stretches over to form an infinite loop. This makes space for two diagonal viewing decks from which passengers can look out towards works of art along the river banks.
