Not long ago, my husband and I were at a restaurant in Massachusetts. At a nearby table, a man and woman were discussing a large yacht they had seen moored in Boston Harbor, which intrigued them. They made a plan to go back the following day and look at the boat's HIN number so they could get more information.
Since we're not boaters, we're curious what they meant. What is the HIN number, and what does it tell about a boat?
