A one-tug assist at the Soo Locks from a Great Lakes Towing tug (typically the
Missouri) seems to be a relatively standard operating procedure for oceangoing vessels, or at least the larger ones. It's been a common sight there since at least the 1990s and likely goes back farther back then that. Larger oceangoing ships (570'+ in length, 74'+ in beam) started becoming regular visitors to the Lakes in the early to mid 1970s. If oceangoing vessels weren't already getting regular tug assists at the Soo Locks by the mid '70s, that would be a good guess for when the practice became common.
