the height of the timber deck cargo above the weather deck on a ship within a seasonal winter zone in winter should not exceed one third of the extreme breadth of ship.
3.2.2 The height of the timber deck cargo should be restricted so that:
.1 adequate visibility is assured;
.2 a safe margin of stability is maintained at all stages of the voyage:
.3 any forward facing profile does not present overhanging shoulders to a head sea; and
.4 the weight of the timber deck cargo does not exceed the designed maximum permissible load on the weather deck and hatches.
3.2.3 On ships provided with, and making use of, their timber load line, the timber deck cargo should be stowed so as to extend:
.1 over the entire available length of the well or wells between superstructures and as close as practicable to end bulkhead
.2 at least to the after end of the aftermost hatchway in the case where there is no limiting superstructure at the after end;
.3 athwartship as close as possible to the ship sides, after making due allowance for obstructions such as guard rails, bulwark stays, uprights, pilot boarding access, etc., provided any area of broken stowage thus created at the side of the ship does not exceed a mean of 4% of the breadth; and
.4 to at least the standard height of a superstructure other than a raised quarterdeck.
It contains stability of ship during its damaged condition and capacity to resist damage situation caused by flooding due to the water overflow into bilges
