Question 69

The Correct Answer is B **Why Option B ("Snatch block") is correct:** A **snatch block** is specifically designed with a hinged side plate (or cheek) that can be opened. This feature allows the block to be attached to a taut line or a 'bight' (a loop or slack section) of the line without having to reeve the line through the block end-to-end. The block can be "snatched" onto the line, hence its name. **Why the other options are incorrect:** * **A) Bight block:** This term is not a standard or proper name for a block type used in rigging. The term "bight" refers to the loop or bend in the line itself. * **C) Heel block:** A heel block (or mast heel block) is a specialized block typically fixed near the bottom or "heel" of a mast or structural member. While it guides a line, it is a fixed block and does not open to receive a bight of line. * **D) Gin block:** A gin block (sometimes just "gin") is a heavy, fixed block or pulley, often used in construction or heavy hoisting (like a permanent hoisting system). It is a closed block and cannot be opened at the shackle end to receive a bight of line.
