Too broad in the beam

A ship was fixed, via an Italian ship broker, to carry steel pipes from Toronto to Garston, United Kingdom.  The day after the fixture had been concluded it was realised that the Italian broker had given the discharge port as Liverpool.  Garston is part of Liverpool, but is a separate port in the River Mersey which is accessed by locks.  The maximum beam for ships transiting the locks is 19.5m and the ship’s beam was 20m.  The charterparty was cancelled and the broker was faced with claims from both the owner and the charterer.  The owner claimed US$ 75,000 for loss of profit and the charterer claimed a further US$ 39,000, for the increased freight paid to the substitute ship.
