When ship is chartered by a seller for the delivery of an export order, then the description of the type and quantity of cargo is likely to be specific, e.g. 10,000 metric tonnes of Welsh anthracite. On the other hand, where the object of the charter is a more general trading venture, then the charterer may be permitted to select one or more from a specified range of cargoes, e.g. ‘wheat and/or maize and/or rye’, or may even be entitled to ship ‘any lawful cargo’. In these latter cases he will probably be required to ship ‘a full and complete cargo’, that is the maximum amount of that particular cargo that the vessel can carry. Should a fixed amount of cargo be specified, such as 10,000 metric tons, it is usual to qualify the figure with a permitted allowance of plus or minus 5 per cent. Should the charterer fail to supply the required quantity of cargo, he will be liable to pay compensation for the shortfall in the form of dead freight.
