Question 1708 Deck Safety

The correct answer is A) a continual worsening of list or trim. Progressive flooding is indicated by a continual worsening of the vessel's list or trim, as the flooding causes an ongoing change in the vessel's stability and balance. This is the key characteristic that distinguishes progressive flooding from other issues like excessive list/trim or draft, which may have other causes. The other answer choices do not directly indicate progressive flooding itself, though they may be symptoms of it. Maintaining awareness of changing list and trim is critical for identifying and addressing progressive flooding in a timely manner.
