There’s never a dull moment for Capt. Don Coleman. Up until this spring, Coleman was the owner of a successful local commercial diving and salvage operation, Blue Diving & Salvage, which got its start as a result of the Gulf oil spill. Now the US Navy veteran is growing his business and moving into the recreational side of boating with the opening of TowBoatUS Mobile, Alabama, an on-the-water towing company that helps boaters, sailors and anglers get safely home when they have trouble on the water. Since his opening a few weeks ago there’s been no shortage of customers.
