PER HATCH PER DAY

The expressionist used to calculate lay time with reference to the number of cargo hatches serving cargo compartments on the vessel. Lay time is to be calculated by multiplying the agreed rate per hatch of loading/discharging the cargo by the number of ship?s hatches and dividing the quantity of cargo by the resulting sum. Thus, Lay time = Quantity of Cargo/Daily Rate x Number of Hatches = Days; A hatch that is capable of being worked by two gangs simultaneously shall be counted as two hatches.
