at the Albert dock, the Germans building tunnels in 1942 to house fuel containers at La Vallette, the tunnels now form a museum. Fish Quay A purpose built quay built in 1987 with a reinforced concrete deck supported on piles with pontoons, built out from the Castle Pier to provide facilities for the small number of local fishing boats. Local yachts Two marinas are dedicated to local yachts and motor boats. The smaller original 1975 Albert Marina, located between the Castle and Albert piers and the newer Queen Elizabeth II Marina located north of the St Julian's Pier which was opened by Her Majesty Queen Elizabeth II in 1989. Both marinas have retaining sills. Visiting yachts Visiting tourist yachts and motor vessels can tie up to pontoons inside the inner harbour, which has a fixed barrier to maintain water in the harbour at low tide, or may moor against outer harbour deep water pontoons. St Peter Port marina is the largest marina in the British Isles, it hosts over 10,500 visiting yachts every year. Cruise ships The island has become a regular destination for cruise ships with over 100 ships arriving between April and October and is the largest tender port for cruise liners in Europe. The restricted size of the harbour will not allow cruise ships to enter resulting in the ships needing to anchor in the roads. The disembarkation of passengers, mainly using their own ships tenders was, until 2014 using a ro-ro ramp on the White Rock pier until an alternative pontoon and ramp were installed attached to the Albert Pier. Initially the ramp caused complaints as it was considered too steep to passengers to climb when tides were very low, in 2015 this was rectified with a longer ramp which reduced the gradient. Businesses are developing for transporting and entertaining the 130,000+ annual visitors, with some queues being experienced on days when two large ships arrive on the same day.
