Nova Scotia's sailing ambassador, the Bluenose II, relaunched September 29, 2012 in Lunenburg, Nova Scotia fitted with pollution-free water lubricated stern tube and rudder bearings. The extensive two-year $15.9 million restoration work was done by the Lunenburg Shipyard Alliance, made up of Covey Island Boat Works, Snyder's Shipyard and Lunenburg Industrial Foundry & Engineering. The rebuild of the iconic vessel meant all new installation of many aspects including stern tube and rudder applications. Specifically requesting water lubricated bearings, the Bluenose II now has a pollution-free stern tube and rudder bearing system.
A fair bit of engineering went into the relaunch project to better fit the vessel with pollution-free bearing solutions. Each shaft of the twin screw stern tube was fitted with three water-lubricated COMPAC bearings; two in the stern and one in the strut. Grease was eliminated from the rudder by using SXL in the four pintle bearings and eight washer-type bearings. Thordon SXL bearings were also installed in the upper rudder stock of the vessel.
Avalon Marine Limited, Thordon Bearings' authorized distributor for Canada's east coast, was heavily involved early on with the recommendation and design process of the vessel's propeller shaft and rudder system.
