🔍 Key Concepts

• Basic parts of a triangular sail: head, tack, clew, and the three edges • Names of the sail edges: luff, leech, and foot • Where the sail attaches to the mast versus the boom or stays

💭 Think About

• Look at where edge A is in relation to the mast and the wind — is it the leading or trailing edge of the sail? • Ask yourself which edge normally has telltales and is the farthest aft when the boat is sailing upwind. • Match each choice to what it actually refers to: corner hardware vs. leading edge vs. trailing edge.

✅ Before You Answer

• Be sure you can point to the three corners of the sail and name them: head, tack, and clew before naming the edges. • Verify which edge is along the mast or forestay (that name is one option in the answers). • Confirm that the remaining edge, opposite the luff, has a specific name that is also one of the choices.
