U.S. Coast Guard boats are often emergency vehicles on the water. While they are used to enforce laws and patrol the waters, they are commonly called in when a boat is in distress. Fires, medical emergencies, and capsized vessels may be all in a day’s work for the coast guardsmen aboard a coast guard boat. Readers are introduced to these important first responders on the water through accessible main text. Full-color photographs support the engaging information and show off the many different kinds of boats the U.S. Coast Guard uses to keep the country’s waters safe.
