I’m not a ship engineer but I do know that ships are not built to be suspended from the ends. I guess in the worst case the hull breaks which would mean the canal to be blocked for quite a while.
That's usually only a real problem when the ship is suspended in the air, between wavetops. This one is still in the water, though maybe it has a little less support in the center than normal
Ships actually are designed to be suspended from the ends. Ocean going vessels are going to experience wave crests which can be any length apart, including the full length of the ship.
