The mainsheet is attached to the boom, and is used to control the mainsail. In a rig with no boom on the mainsail, the mainsheet would attach directly to the mainsail clew. A mainsheet is a line connected to the boom which allows a sailor to control the speed of a boat. The jib sheet attaches to the clew of the jib, and controls it. The jib has ...
The mainsail does not have a boom, has nine full battens, and is controlled by a main sheet with a 7:1 mechanical advantage. The jib sail has two short battens, and is controlled by a jib sheet with a 2:1 mechanical advantage. The main sheet block and both jib sheet blocks have a ratchet and a cleat.
Radio control may be used in many locations. Typically two controls are provided for sailing yacht models, a general–purpose small servo for rudder control and a specialized sail winch to draw in the mainsheet and jib. Motorized craft control rudder and throttle, and perhaps other functions such as reversing, lighting, and mechanical novelties.
Running rigging on a sailing yacht: 1. Main sheet 2. Jib sheet 3. Boom vang 4. Downhaul 5. Jib halyard. Rigging comprises the system of ropes, cables and chains, which support and control a sailing ship or sail boat's masts and sails. Standing rigging is the fixed rigging that supports masts including shrouds and stays.
As the mainsheet is loosened to increase the horizontal angle of the boom and sail, the mainsheet becomes horizontal and exerts less downward force. A vang works with the mainsheet to apply the downward force on the boom at all horizontal angles, allowing the mainsheet to be used to control the horizontal angle of the boom effectively.

Easing the main sheet increases twist and the twist is usually adjusted so that the aft end of the top batten in the main sail runs parallel to the boom. The traveller is a track running from one side of the boat to the other upon which sits a car to which the other end of the sheet is attached.
For sailing there are two main, two-speed genoa winches, two secondary winches and one halyard winch. The mainsheet has a 4:1 mechanical advantage, which a fine tuning system with 16:1. There is a mainsheet traveler with a 4:1 car. An 8:1 boom vang is also provided, along with jib tracks.
