This holiday weekend has not been a kind one for ship departures... this one affected a HAL departure from Boston. The upside of this one is the passengers were treated to the annual fireworks display at the Esplanade. If you have to be on a ship that is not getting underway on time, I can't think of a nicer thing to get "stuck" looking at!  This ship is going to miss one port of call but is apparently safely underway now.
