Question 1899 Deck Safety

The correct answer is B) permissible length. The permissible length refers to the maximum longitudinal distance allowed between main transverse bulkheads on a vessel. This is a regulatory requirement set by the U.S. Coast Guard to ensure the vessel's structural integrity and stability in the event of damage or flooding. The permissible length is calculated based on factors such as the vessel's size, construction, and intended service, with the goal of limiting the extent of potential flooding and maintaining the vessel's ability to remain afloat. The other options are incorrect because: A) Floodable length refers to the maximum length of a compartment that can be flooded without the vessel losing its ability to remain afloat. C) The factor of subdivision is a calculation used to determine the minimum number of main transverse bulkheads required. D) The compartment standard refers to the minimum requirements for the construction and arrangement of watertight compartments on the vessel.
