The Coast Guard Cutter Marlin, an 87-foot patrol boat home ported at Fort Myers Fla., conducts a patrol off Florida's West Coast. The Coast Guard protects more than 360 ports and 95,000 miles of coastline, America's largest border. Homeland security--especially maritime law enforcement and border control--is the oldest of the Coast Guard's numerous responsibilities and dates back to its founding as the Revenue Cutter Service in 1790.
