Question 1943 Deck Safety

The correct answer is B) upper or weather deck above the main strength deck. The definition of a "spar deck" refers to the uppermost continuous weather deck on a vessel, which is typically located above the main strength deck. This deck is designed to provide structural support for the masts, booms, and other rigging that is mounted on the deck, hence the term "spar deck". The other options are incorrect because: A) refers to the aft-most weather deck, not necessarily the spar deck. C) refers to the lowest continuous deck, which is not the definition of a spar deck. D) refers to a deck of lighter construction below the main deck, which is not the definition of a spar deck.
