First of all, I am not sure where your so-called pecking order comes from or that under COLREGSthat your pecking order actually is right. For example when a sailboat is over taking a powerboat, the sailboat is the burdened vessel. Further I am not sure that "vessel fishing" is a stand on vessel on COLREGS. I believe that commercial vessels that are fishing are covered as commercial vessels with limited manueverability. Private fishing vessels should be afforded the courtesy when possible but are not actually given privileges. Headboats and sportfisherman probably fall in the same category as private yachts that are fishing.
