Boxship or tweendecker?

A shipbroker Member had represented the same charterer for many years and the same broker had always handled the account.  The business involved fixtures for cargoes of borax for which the charterers required ships with box holds.  The charterer approached the Member for a ship and, in the absence of the regular broker, three ships were offered.  Two of the ships were described as having box holds, whereas the third (and cheapest) was silent on the subject.  The charterer chose the third ship.  When it arrived at the loadport it was found to be a tweendecker and was rejected by the charterer.  The Club settled the owner's claim for damages.
