May have to change this to include NPS!
From Boatsafe boating course:
Alaska - Marine Law Enforcement
State peace officers, including the Alaska State Troopers and State Park rangers, enforce state boating laws. U.S. Coast Guard boarding officers enforce federal boating laws.
Whenever approached by these officers boaters must stop, or slow to a speed sufficient for safe steerage only, and permit the officer to come alongside
to check for registration and safety equipment. Resume speed only when out of the vicinity of or at the direction of the officer.
While safe boaters will find these officers both helpful and professional, violators can expect to be cited.
