Question 2491 Deck General

The correct answer is C) Condition of trim in normal operation. The required freeboard of a cargo vessel is affected by factors such as the season of the year (which determines the wave conditions), the density of the water it operates in, and the geographic zone of operation (which affects the expected weather conditions). However, the condition of trim in normal operation does not directly affect the required freeboard, as the freeboard is determined based on the overall vessel dimensions and the expected operating conditions, not the specific trim of the vessel during normal use. The other options A, B, and D are correct factors that can affect the required freeboard of a cargo vessel, as they influence the expected wave and weather conditions the vessel will encounter.
