With the jib leads moved forward, the leech tension and foot fullness of the jib become:

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

Answer: (A)

Shaping the jib by where its leads are positioned changes how the sail loads along its edges. When the jib leads are moved forward, the sheet pulls more toward the bow on the lower portion of the sail. That forward pull tends to tighten the trailing edge (the leech) and also increases the curvature along the bottom edge (the foot), making the foot fuller. So the leech carries more tension and the foot gains fullness. In different conditions you might adjust differently for power or performance, but this forward lead position specifically produces more leech tension and a fuller foot.
