A US Naval submarine leaves Port Everglades on April 29, 2013 accompanied by the Coast Guard and port harbor pilot (foreground) and a tugboat. A Fort Lauderdale Marine Unit boat, far left, accompanied the sub out to sea and moored with its blue light on to keep boat traffic at bay as the sub moved in a narrow channel a few hundred yards offshore. The sub has been seen close to shore the past week or so off John U. Lloyd State Park. It stayed above-water for most of the time.
