If you move the jib leads forward, what happens to the jib's leech tension and foot fullness?

• A. More leech tension and fuller foot
• B. Less leech tension and flatter foot
• C. More leech tension and flatter foot
• D. Less leech tension and fuller foot

Answer: (A)

Moving the jib leads forward changes where the sheet pulls on the sail, tilting the sail’s shape to be deeper at the bottom and pulling the leech tighter. A forward lead angle increases the force along the trailing edge, tightening the leech, while also deepening the sail’s draft toward the foot, making the foot fuller. In short, you’ll get more leech tension and a fuller foot when the leads are moved forward. If you needed to depower, you’d typically move the leads aft to flatten the sail and reduce leech tension.
