Question 468 Deck General

The correct answer is C) at the head of the boom. The head block is a pulley system located at the head (or outer end) of the boom. This pulley system is used to raise and lower the boom, which is a horizontal spar that extends outward from the mast to support the sail. The head block allows the crew to control the position and angle of the boom, which is crucial for sailing and maneuvering the vessel. The other answer choices are incorrect because: A) the base of the boom is where the boom connects to the mast, not where the head block is located; B) the head of the mast is where the topmast or masthead is located, not the head block; and D) the jack staff is a short vertical pole at the bow of the vessel, which is not related to the location of the head block.
