Tonnage law

[Agnes]

The vessel, or vehicle with the greatest gross [tonnage] has the right of way.

Based in [part on] the [navigation] rule about ships restricted in ability to maneuver and how other ships need to stay away. And the reality of if there is a collision between two or more vehicles the smaller vehicles will take more damage than the larger vehicles. And that greater amount of damage is shared with the occupants of the smaller vehicle.
