Dredge 'Port Nelson' - 1928

Essential to Port Nelson's harbour construction was a large and efficient dredge. Polson Iron Works in Toronto was commissioned to build (1913) the dredge Port Nelson, length 180 feet, beam 44 feet, draught 6 feet, weighing 1,155 tons and with a suction line two feet in diameter. She was thought to be the most powerful dredge in the world when she was towed into Port Nelson in September 1913. No sooner had she been released from her tow than she beached on some rocks, which caused a great deal of damage to the flat bottom structure. The dredge shifted many thousands of cubic feet of mud for several years after her mishap.
