There was a time when ships chased and caught the wind for profit, carrying cargo to the world.  Like skinny ties, the past is circling back again.  In Norfolk harbor, Virginia, there’s a tugboat unlike any other.  It’s called a Tugantine.  Part tugboat.  Part sailboat.  It started as a joke.  When her captain, Lane Briggs, noticed a 28 percent saving in fuel, the sails stayed on.
