A Boat off the Coast — Stephen Dobyns

In high school Brian had always thought Tucker a hero a little wild, great at football, always fun. Fifteen years later Brian is married, a supervisor at a chicken factory, and a daily lobster fisherman off the coast of Maine. Tucker, back from Vietnam, has also married; but his "heroism" is seen through by Brian's wife, Margaret. The two young men get involved in cocaine smuggling, Margaret's sister is conquered by Tucker, and all hell breaks loose when Tucker tries to cheat the suppliers.
