The windward line, or guy, is attached to the corner called the tack of the sail, and is stabilized by a spinnaker pole. The leeward (downwind) line is called the sheet. It attaches to the clew of the spinnaker and is used to control the shape of the sail. The spinnaker pole must be moved in each gybe, and is quite difficult for beginners to ...
These sails make it possible to use one sail as spinnaker and Gennaker. These sails can be used between 70 and 180 degrees to the wind. Relieving the pressure on the bow and the stabilizing effect of the Parasailor and Parasail improve the effect of the rudder and decrease the rudder throws needed. [2] The Parasailor has a double-layer wing ...
When attached to a long bowsprit or "prod", an asymmetrical spinnaker can be larger than a conventional spinnaker, since it can be carried further forward of the boat than is possible with a conventional spinnaker pole and the foot of the sail can extend to deck level. [1] Many modern sailboats have retractable bowsprits to enable this expansion.
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 470 (Four-Seventy) is a double-handed monohull planing dinghy with a centreboard, Bermuda rig, and centre sheeting.Equipped with a spinnaker, trapeze and a large sail-area-to-weight ratio, it is designed to plane easily, and good teamwork is necessary to sail it well.
Guy (red arrow), controlling the spinnaker pole. A guy (probably from Dutch gei, "brail") is a line attached to and intended to control the end of a spar on a sailboat. [1] On a modern sloop-rigged sailboat with a symmetric spinnaker, the spinnaker pole is the spar most commonly controlled by one or more guys.
This configuration is optimized for upwind sailing efficiency. For downwind sailing without a spinnaker, the larger mainsail of a fractional rig has a significant advantage over a masthead rig but a disadvantage when spinnakers are flown. Many newer high-performance fractional rig sailboats, fly the spinnaker or the gennaker from the masthead ...
The 49er carries three sails: a mainsail, jib, and spinnaker. The main and jib combined are 20 square metres, fully battened and made of reinforced Mylar (film polyester). The main was redesigned in 2007 from a full, curved roach plan to having a square on top in order to provide more sail area and to control more shape adjustment.
