As far as the ferries in puget sound they are an extension of the freeways so it's just like driving down the freeway
Nothing to report to ANYONE
I believe the ferry that leaves Washington to go to Alaska is the same.
Alaska says as a "Walk-on passenger" you must check it....
Alaska Marine Highway System - Travel Policies
Alaska DOT said:Walk-on passengers traveling with legal firearms or weapons on AMHS vessels are required to check these items with an AMHS loading officer. All firearms must be unloaded and ammunition stowed separately from the firearms.
