Question 2106 Deck General

The correct answer is D) Double luff tackle. The illustration D029DG is showing different types of tackle configurations, and tackle number 5 is a double luff tackle. This is a type of purchase system that uses two sheaves or pulleys to increase the mechanical advantage and allow heavier loads to be lifted. The "double luff" refers to the fact that the line passes through the blocks twice, creating a four-part line. This provides more lifting power compared to a single-part line. The other answer choices do not accurately describe the configuration shown in the illustration. A 3-2 purchase, two-fold purchase, and four-fold whip are different types of tackle systems that have distinct characteristics not matching the double luff tackle depicted.
