Right of way?

We were out boarding on the river with a channel in it. We had a rider in tow and riding on the edge of the channel and a boat is coming at us head on. We notice it about a 1/4 mile way. Since we are towing we just hold our course and expect the other boat to yield to us. Well the other boat as it gets closer is a NJ State Police boat and he just holds his course and does not move. As I realize he is not moving over I move. As he passes us he pulls us over and says how we are in the wrong for not yielding to him.

I thought if we are under tow with a rider already in tow we would have the right of way? Thoughts on this?
