Where can i find boat rules or laws?

sat. my fishing friend and i headed for the skykomish river for steelhead the process for drift boat fishing is you drop off one vehicle at the take out then take the other with boat and trailer to launch up river do your drift beach boat and take pickup back to launch gtab pickup and trailer, you get the idea, well when i parked my truck at sultan take out launch my buddy pulls in to pick me up, there was a snohomish county sheriff [marine safety checker] i may comment i was glad of his presents see as how it was 4;30 am he then proceeded to do a safety check on 16ft drift boat going thru his list of items we didnt have a whistle or throw ring anyway my point is WHY retain fisher men at that hour when he darn well the reason to be there that early was to be first on water two things where can find the rules for drift boats and second how can i lodge a complaint, found out later from wsfw that he is well known for pissing fisherman off this way he did it at monroe ramp on fathers day
