🔍 Key Concepts

• Count how many sheaves (pulleys) are in the upper and lower blocks of tackle 11 and how many parts of line are supporting the load. • Recall the standard names: gun tackle, luff tackle / double luff, and what a three-two purchase describes in terms of sheave arrangement. • Remember that topping lift is usually the name of a line’s job on a boom, not primarily the mechanical arrangement of the blocks.

💭 Think About

• Look closely at tackle 11: How many sheaves are in each block, and is the standing part secured to the upper or lower block? • How many working parts of the fall (moving line segments) are actually taking the weight of the load in tackle 11, and which option’s name matches that mechanical advantage? • Which of the listed choices describe a type of purchase (tackle arrangement) and which one mainly describes a function on a vessel rather than a specific block-and-tackle layout?

✅ Before You Answer

• Verify the exact number of sheaves in the upper and lower blocks for tackle 11 and match that to the standard names of purchases. • Eliminate any option that refers mainly to a function (what the line does) instead of the mechanical setup you see in the drawing. • Confirm which named purchases (gun tackle, double luff, three‑two purchase) involve single vs. multiple sheaves in each block, then match that pattern to illustration 11.
