Hi, Daniel.
The Narrowboat Simulator is way too specific at the moment to be easily extended to include the "Suez Scenario".
Anyway it is an interesting challenge to think about solutions for this topic. Personally, i didn't know until this event that the Suez Canal has no locks. I would have thought that this would cause way too much (tidal) current in the canal but obviously, that isn't the case.
My personal idea would be adding many tons of salt to the canal water (close to the ship) to increase the lift of the water and raise the ship a bit.
