Question 609 Deck General

The correct answer is B) gooseneck. The gooseneck is the fitting that allows a boom to move freely both vertically and laterally. It is a pivoting connection that attaches the boom to the mast, enabling the boom to pivot and swing as needed during sailing operations. The other answer choices are incorrect because: A) A spider band is a fitting that secures the end of a boom to the mast. C) A lizard is a type of line used to control the position of a boom. D) A swivel is a fitting that allows rotation in a single plane, not the free movement in two planes that a gooseneck provides.
