The boats moored in the floating museum section of the Port-Musée de Port-Rhû are accessible to visitors. These include the large Breton lobster boat Notre-Dame de Rocamadour, on board which it’s well worth climbing down to its machine room and ice room; the British steam-powered tug St-Denys, with its impressive machinery; the Brest-based gabarre Dieu Protèg, and the Thames barge Northdown.
