11.1 Clause 1 of the New York Produce form sets out the owners’ principal obligations with respect to the running and upkeep of the ship during the charter period. Clause 6 of the NYPE 1993 form contains the same obligations, though it also adds an express obligation on the owners to maintain “a full complement of officers and crew”: see Clause 6, Lines 78 to 82. Clause 3 of the Baltime form contains substantially the same obligations. Where, as is common, the charter incorporates the Hague or Hague-Visby Rules, those rules will also impose on the owners a duty to exercise due diligence to make the ship seaworthy before and at the beginning of each voyage performed under the charter: see paragraphs 11.15 and 34.13, below.
