Leech line

A small line in the leech used to adjust its tension.

How to sign

Use Dominant R-hand: rope classifier. The base or passive hand is Non-dominant 1-hand: leech edge, or established sail plane. Set the leech edge from head to clew. Place the rope classifier at its upper portion. Trace down the leech, then make one small inward pull to show tension adjustment. Stop with the rope held taut; do not use a long release movement. Place the leech edge. Use an R-hand rope classifier to trace that edge, then make a small PULL movement to show tension adjustment.
