Cindy and Jon Smith of Southport both have their tug licenses but these days they are mostly shore-based running Interport Towing & Transportation. The jointly owned company has three tugs that do coastal towing as well as providing support for marine construction. They also have a Tier 2-compliant Cummins-powered crew boat that does standby and transport work for dredging and construction work. With this diversity there is always a project underway. Most recently this has been the repower of their tug Lucinda Smith.
