When I was stationed at NAS Pax River, I did a lot of boating on the Chesapeake Bay. There is a whole lot of ship traffic going up to Baltimore. I always went but the simple rule that the biggest boat wins. Even when sailing, you give way to 100 ton ships, not the other way around.

Same rules/laws apply on land in real life as well. Rule #1 is ALWAYS YIELD THE RIGHT OF WAY TO A LARGER VEHICLE!
I used to drive for a trucking company, and one day I had to take two 55-gallon drums (weighing 580lbs. each) to a coal mine in WV. I drove for 12 miles from the entrance of the mine to the guard house, then had to take a 20 minute "mine safety course". After that, they gave me a map, circled the building I had to deliver the drums to, 8 miles further into the mines.
The basic rules taught to me from the "mine safety course" were: All mine traffic has the right of way. If you hit anything, it's YOUR fault. If anything HITS YOU, IT'S YOUR FAULT! Stay alert, be careful, stay out of the way and don't hit anything....
Somebody should have given the "mine safety course" to these nimrods on the batboat....
