A “filled compartment, untrimmed" is a compartment
which is filled to the maximum extent possible in way of the hatch
opening but which has been granted a dispensation from trimming outside
the periphery of the hatch opening either by the provisions of regulation VI/3(c) for all ships, or by MSC/Circ.323
on the dispensation from trimming under-deck voids in filled cargo
holds of specially suitable ships. For other information applying
to such compartments, refer to guideline No.2.
