The amount of rake is measured from the back of the mast at the partners to a plumb line hanging from the main halyard. A high-clewed genoa used when reaching in heavy winds. The area of a mainsail that protrudes beyond a straight line from the head to the clew. The roach is supported by battens. Lami-nated to Mylar, scrims make strong, lightweight sail cloths.
Scrims are distinctive since there is empty space between threads.
The name comes from the flat piece of cloth that connects the bottom of the sail to the boom. Wires that support the mast athwartships. Strut attached to the side of the mast, which amplifies the shrouds ability to support the mast. Tightening the afterguy, which pulls the spinnaker pole back. Also see Shroud.
