What is the mainsail leech?
Modern sails may come with a standard leech line (leech control) that runs under the back edge of the mainsail. This line is usually fixed at the head of the sail, and the other end can be cleated near the clew of the sail.

What is a cunningham on a sail?
The cunningham controls the fore and aft position of draft in the mainsail or genoa and works together with the traveler, mainsheet, outhaul and vang to optimize sail shape and increase boatspeed. Cunningham controls lead to the crew to encourage adjustment as wind speed changes.
