Rule number one of the rules of the road.

If it is bigger than you it's got the right of way.

Sure under some circumstances the rules may say you are the one with the right of way. But size difference is a matter of physics not law. If you go head to head with something the size of a tanker you will lose.

When I was on a sub we were coming into port. Some idiot in a sailboat decided to claim right of way. Well a warship always has the right of way. But besides that we could not have maneuvered well enough or stopped fast enough. He finally realized he would lose and veered off. If he had not he would have been run over.
