Usually a shroud will connect at the top of the mast, and additional shrouds might connect partway down the mast, depending on the design of the boat. Shrouds terminate at their bottom ends at the chain plates, which are tied into the hull. They are sometimes held outboard by channels, a ledge that keeps the shrouds clear of the gunwales. [1] [2]
The term "marine canvas" is also used more narrowly to refer specially to boat cover products. When referring to materials "marine canvas" is a catch–all phrase that covers hundreds of materials, for instance: acrylics, PVC coated polyester, silicone treated substrates and many coated meshes suitable for outdoor use.

The first generation, built around 1970, included a backstay and was used on many production boats. A patent application for the B&R rig was submitted in 1973 and was granted in 1975. [ 1 ] A second generation eliminated the backstay but used solid, deck-mounted struts to brace the lower mast section.
Sail components include the features that define a sail's shape and function, plus its constituent parts from which it is manufactured. A sail may be classified in a variety of ways, including by its orientation to the vessel (e.g. fore-and-aft) and its shape, (e.g. (a)symmetrical, triangular, quadrilateral, etc.).
The mast of a sailing vessel is a tall spar, or arrangement of spars, erected more or less vertically on the centre-line of a ship or boat. Its purposes include carrying sails , spars, and derricks , giving necessary height to a navigation light , look-out position , signal yard , control position , radio aerial or signal lamp . [ 1 ]
Four sets of swept and fixed spreaders on a large yacht. A spreader is a spar on a sailing boat used to deflect the shrouds to allow them to better support the mast. [1] The spreader or spreaders serve much the same purpose as the crosstrees and tops in a traditional sailing vessel.
