If deviating for owners’ purposes, for example to collect an engine part or crew member, the vessel will usually be off-hire from the moment of the deviation until ready to resume service in a position no less favourable to charterers.
In this case the exact times, positions and fuel r. o. b. (1) at the start of the deviation and (2) on rejoining the route should be recorded, since a deduction from hire will be calculated on the basis of fuel used in the deviation, including FO and DO at the port deviated to. If the deviation was for charterers’ purposes or stress of weather, however, there should be no deduction from hire.
