Although the St Lawrence (including the Welland Canal) locks are specified as being able to accommodate 740 foot ships, they are actually quite a bit longer. The extra distance is a safety buffer for normal operations/ship entry speeds and includes a 60 (or more in some cases) foot distance between the arrester cable and the downstream lock gates. It looks like some of the locks (#7 for example) could accommodate a ~900 foot ship if it were allowed to enter, but that's not going to happen.
The tow entered the locks VERY slowly under the control of the highly maneuverable tugs, so the mandatory use of the arrester cable was waived, freeing up more space in the lock than usual, but it was still a tight fit, requiring the overlapping of tapered bows/sterns as previously noted.
The oddball Welland Canal Lock 8/"Guard Lock", at 1,148 feet, handled Victo and all three tugs at the same time, with room to spare
