Navy & Survey Vessels Shelter from Weather at Dun Laoghaire Harbour's Deep Water Berths 20th May 2021 Dun Laoghaire harbour berths occupied today by the Navy's LE George Bernard Shaw (centre) and the red hulled Danish Survey vessel the Arctic Ocean (right) along with the Dublin Bay Cruises sightseeing ferry No sooner than the Belgian fishing trawler fleet departs Dun Laoghaire than the Harbour's Carlisle Pier and St. Michael's Wharf are in use again such is the current demand for deepwater berths on Dublin Bay. Now, as south-east winds are forecast to gust to 50 knots on Dublin Bay today, the harbour berths are occupied by the Navy's LE George Bernard Shaw and the Danish Survey vessel the Arctic Ocean along with the Dublin Bay Cruises sightseeing ferry, as a refuge from the weather.
