Definitely nothing good.

Showing the same size explosion at some US ports (usually avoiding military ports for obvious reasons):

• NYC, Pier 11 ferry terminal - takes out Battery Park and the Brooklyn Bridge, and damages the Manhattan Bridge
  
• colliding with the RiverLink Ferry between Philadelphia and Camden - takes out the Battleship New Jersey, Rutgers University - Camden, and the Benjamin Franklin Bridge (I-676)
  
• Harbor East ferry terminal, Baltimore - takes out the entire Inner Harbor, including the USS Constellation and USCG Chesapeake
  
• Galveston Harbor
  
• Cleveland Harbor
  
• directly above the Detroit-Windsor Tunnel, on the border (cheating here - this isn't a harbor or port)
  
• Navy Pier, Chicago
  
• Duluth harbor
  
• Seattle Ferry Terminal
  
• Pier 41 ferry terminal, San Francisco
  
• San Pedro ferry terminal, LA
  
• North Harbor, San Diego - takes out the airport and damages the USS Midway
  

I think the lesson here is "don't ship explosives by ship."
