I saw that too. I thought the flight deck overhang would not preclude the use of the seaway, but now I see below that the entire ship sits below the top edge of the lock. Oh well.
I wonder if the new River class destroyers will be able to transit the Seaway. At over 8,000 tons, the Rivers are the largest warships ever produced in Canada. The
River class is narrow and short enough to fit, but with a draught of 8 m (26 ft 3 in), or 3 in away from the max depth, they might be scraping the bottom. And that 8 m draught is presumably in sea water, meaning that the ship will displace about 2.5% more water, and thus sit deeper in fresh water. Perhaps they can lighten the ship for the transit.
@kEiThZ thoughts?
