Many mast-aft rigs utilize a small mainsail and multiple staysails that can resemble some cutter rigs. A cutter is a single masted vessel, differentiated from a sloop either by the number of staysails, with a sloop having one and a cutter more than one, or by the position of the mast, with a cutter's mast being located between 50% and 70% of the way from the aft to the front of the sailplan ...
The Coronado 15 is a recreational planing sailboat, built predominantly of fiberglass. It has a fractional sloop rig with black anodized aluminum spars. The mast is flexible and supported by stainless steel standing rigging. The hull has a spooned plumb stem, a vertical transom, a transom-hung rudder controlled by a tiller and a retractable ...
The gooseneck is the swivel connection on a sailboat by which the boom attaches to the mast. The boom may pivot in any direction, from side to side or up and down, by swiveling on the gooseneck. [1] The gooseneck may be a two-axis swivel as pictured. Having an integrated shackle for the tack is common. Goosenecks on older rigs may be formed by ...
When the boat jibes, the spinnaker pole will be moved from one side of the boat to the other, causing the sheet to become the guy and vice versa. A foreguy may also be used to control the height of the spinnaker pole. It is attached either to the end of the pole or to a bridle on the bottom of the pole, and runs through a padeye on the foredeck ...
The earliest B&R rig was the result of wind tunnel tests and research by Lars Bergstrom and Sven Ridder at Sweden's Royal Institute of Technology. [6] 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]

C. A. Marchaj, a researcher who has experimented extensively with both modern rigs for racing sailboats and traditional sailing rigs from around the world, has done wind tunnel testing of scale models of crab claw rigs. One popular but disputed theory is that the crab claw wing works like a delta wing, generating vortex lift. Since the crab ...
