She has primarily been operating on the fresh water seas of the Great Lakes since being purchased by Lower Lakes Towing of Port Dover in 2011 while named TECUMSEH after the First Nation's Chief who played a major role in Canada's successful repulsion of an American invasion in the War of 1812
According to the International Regulations for Preventing Collisions at Sea (and narrow channels), no vessel ever has "Right of Way" over other vessels. Two power-driven vessels meeting each other head-on (meaning seeing the other vessels masthead and running lights in line with each other) both vessels are required to alter course to the starboard so that they pass on their port side and avoid colliding with each other. As the saying goes "If you see three lights ahead, starboard wheel and show your red". If one of the two power-driven vessels are crossing, the vessel which has the other on the starboard side must give way and avoid crossing ahead of her. The saying is "If to starboard red appear, 'tis your duty to keep clear"..."Act as judgement says is proper: port or starboard, back or stop her". That can be easier said than done because if there's no room, time to turn or stop the heavy ship, a catastrophic collision could occur.
Such was the case on July 30th, 1962 when after leaving her berth in Detroit, the 450' British bulk carrier MONTROSE crossed in front of the downbound tug & barge, B.H. BECKER & ABL 502 while attempting to veer across the Detroit River to enter the upbound channel. The barge, hauling 1,600 tons of cement clinker out of Port Huron, tore a 48' hole the port side of the less than two years old MONTROSE. Taking on water immediately and caught in the Detroit River's strong current, the crippled MONTROSE was pushed downstream until she ran aground and rolled over onto her starboard side beneath the Ambassador Bridge. Fortunately no souls were lost, and though the MONTROSE was eventually raised and then repaired over that winter in Lorain, Ohio, when she got underway, her name was changed to CONCORDIA LAGO and she never sailed on the Great Lakes again.
