🔍 Key Concepts

• Boom components (heel, head, spider band, cargo hook) and their locations • Relationship between a boom and the mast/kingpost it is attached to • Function of a heel block in cargo handling gear

💭 Think About

• Think about which end of the boom is fixed to the ship and which end moves over the hatch or pier • Ask yourself: where would it make the most sense to place a block that redirects the load from the boom to the ship’s structure? • Compare the roles of the heel, head, and spider band—how does each part interact with the rigging?

✅ Before You Answer

• Be clear on which end of the boom is the heel and which is the head • Visualize the path of the cargo runners and topping lifts along the boom • Eliminate any option that is clearly associated with the free/movable end of the boom rather than the attached end
