DescriptionOn 20 July 1963 the Bermuda-registered ore carrier was on the St Lawrence River en route from Havre-Saint-Pierre to Sorel, Québec with about 18,300 tons of ilmenite when she collided in dense fog with the British cargo ship Roonagh Head shortly before 03:00 hrs off Petite-Rivière-Saint-François. She sank within eight minutes with all hatches open. Her sinking was so sudden that all navigation crew were trapped in the wheelhouse. 18 bodies were recovered; another 15 remained missing. Her Canadian pilot was also missing. In the fog and night a third ship, the Spanish Conde de Fontamar, struck Tritonica's superstructure. She saved seven survivors.
