 As she was being guided into the harbor, the giant ship caused a large displacement of water which made the moored "SS City of New York" swiftly rise and fall.The motion snapped the mooring cables tethering the "New York" and the ship began moving toward "Titanic".A collision was narrowly averted when one of the tugboats assisting "Titanic" was able to get a line on the "New York"; the tugboat then towed the wayward ship out of the path of the "Titanic".
