A sail batten is a flexible insert in a fore-and-aft sail that provides added stiffness and definition to the sail's airfoil cross-section. [1] The most common use of sail battens is in the roach of a mainsail. The batten extends the leech past the line that runs from the head and the clew of the sail to create a wider sail towards the top.
For a triangular sail the head refers to the topmost corner. [37] A fore-and-aft triangular mainsail achieves a better approximation of a wing form by extending the leech aft, beyond the line between the head and clew on an arc called the roach, rather than having a triangular shape.

This meant a traditional mainsail could be raised no higher than the first point a rope or wire was required to keep the mast upright. Further mainsail area (and height) was obtained by adopting a gaff rig. A mainsail may be fixed to the boom via slugs, cars, or a bolt-rope, or may be "loose-footed," meaning it is only attached at the tack and ...
A mainsail ("mains'l") is a sail attached to the main mast. The principal types include: A square-rig mainsail is a square sail attached at the bottom of the main mast. A Bermuda-rig mainsail is a triangular sail with the luff attached to the mast with the foot or lower edge generally attached to a boom.
