WEST SHIP ISLAND, Miss. (AP) — The Coast Guard says it is searching for a missing boater off of Mississippi, and a grounded boat's GPS system showed where to look.

Petty Officer Alexandria Preston says the 17-foot pleasure craft had nobody on board when it grounded near Gulfport Harbor about 6:45 a.m. Tuesday, with its motor running. But she says the GPS showed a track starting near West Ship Island , a barrier island about 12 miles away.

Preston, a Coast Guard spokeswoman, says three Coast Guard craft, including a helicopter, and the Mississippi Department of Marine Resources are searching for Kevin Anderson.

She doesn't know his age or home town.

Anyone with information that may help is asked to contact Coast Guard Sector Mobile command center at (251) 441-6211.
