Titanic Boat Tours. The Titanic boat tour is run by the Lagan Boat Company.  Scheduled guided Titanic tours take in the historic Harland & Wolff shipyards and the famous Titanic sites around Belfast Harbour. Although many of the riverside Harland & Wolff sheds were demolished in early 2002 and those sites/sights are now gone, their demolition has actually provided a much better view of the Titanic slipways which were previously hidden by these same sheds.
