🔍 Key Concepts

• Topping lift purpose and what causes higher tension in it when a boom is swinging • How boom angle/position changes the load on the topping lift • Difference between controlling horizontal swing versus supporting vertical weight of the boom and load

💭 Think About

• Ask yourself which option most directly reduces the vertical load or leverage on the topping lift when the boom is moving. • Consider which choice mainly helps control side‑to‑side motion rather than changing how much weight the topping lift is carrying. • Think about whether adding more purchase (more parts of line) changes the force in the topping lift, or mainly changes the effort required on the cargo winch or falls.

✅ Before You Answer

• Which option changes the geometry/angle of the boom relative to the mast and deck? • Which option affects the actual force in the topping lift, not just how easy it is to lift the load? • Which rig—preventer, back stay, or cargo purchase—is primarily for controlling swing versus supporting weight?
