For trip-charters designed for specific voyages, it is commonplace to insert an approximation of the voyage duration – e.g. ’45 days’ – although this is normally qualified by the addition of the words ‘all going well’ or ‘about’ or ‘without guarantee’. (Here a word of warning for shipowners and their brokers. Legally ‘about’ will be given a reasonable implication. An actual duration of ’50 days’, for example, could be interpreted as ‘about 45 days’. However, ‘without guarantee’ means exactly that. In effect redelivery after only ’10 days’ is legally satisfactory). Trading Intentions/limits: (Preamble lines 57/62) – Clause 6). The areas of the world in which the vessel is to be employed should be entered – e.g. ‘worldwide, but always within Institute Warranty Limits’ (see Lesson Nine) – as well as listing those countries and parts of the world specifically excluded from the permissible trading area. Where there is insufficient space to type in the full agreed data, it may be necessary to include same in a rider clause, using blank lines in this part of the charterparty to refer the reader to the relevant rider clause. This also becomes a logical point in some charterparties to include limitation to the effect that a vessel must trade always between ‘safe berths and ports’, usually ‘always afloat’. Cargo Intention/exclusions: (Preamble lines 45/56) – Clause 12). Include details of cargoes which can and those which cannot be carried (see reference to cargo exclusions in Lesson Two). Trip time charters often specify the actual cargo to be carried although, if this is only an ‘intention’, a cargo exclusions clause must still be included. Vessel Condition: (Preamble – lines 8/9 and lines 41/454). Just as for voyage charterparties, an undertaking by the vessel’s owners that the vessel is in good condition.
