The U.S. Coast Guard Auxiliary is a volunteer, civilian, non-military arm of the U.S. Coast Guard. It serves the general public through boating safety classes, vessel safety exams, and safety patrols on the water and in the air. 

Members of the Auxiliary have no law enforcement powers and issue no permits or citations.  However they do work closely with law enforcement to ensure the safety of the boating public.

The auxiliary was formed in 1939 and today there are over 27000 volunteer men and women active on the water and in classrooms in over 2000 cities and towns in this nation. Each year they save over 500 lives, assist some 15,000 boaters in distress and conduct more than 150,000 courtesy vessel exams and teach over 500,000 students in boating and water safety courses.
