The spinnaker is raised as normal, but with the sock in place, the spinnaker is unable to catch the wind. Once the spinnaker is raised and the guys are ready to set, the sock is raised, releasing the spinnaker. The sock remains bundled up at the head of the sail while the spinnaker is deployed.
A forestay might be made from stainless steel wire on a modern yacht, solid stainless steel rod, carbon rod, or ultra high molecular weight polyethylene (such as Spectra or Dyneema) on a high-performance racing boat, and galvanised wire or natural fibers on an older cutter or square-rigged ship.

The spinnaker pole is rigged to run from the base of the mast, [1] where there is a special fitting for attaching one end of the pole, out to windward over the side of the boat. There, one of the control lines of whichever sail it is to be used with is run through a fitting on the other end of the spinnaker pole. This allows for more precise ...
A subdivision of the sheet plywood boat building method is known as the stitch-and-glue method, [8] where pre-shaped panels of plywood are drawn together then edge glued and reinforced with fibreglass without the use of a frame. [9] Metal or plastic ties, nylon fishing line or copper wires pull curved flat panels into three-dimensional curved ...
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.).
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.
The Parasailor and Parasail are patented and trademarked variants of a spinnaker sail for yachts. They were designed for cruising couples and short-handed crews and are considered to be easy to handle and well tempered. [1] These sails make it possible to use one sail as spinnaker and Gennaker. These sails can be used between 70 and 180 degrees ...
A symmetrical spinnaker has two sheets, an "active" one and a "lazy" one, in the same way as a jib, but they are attached to the sail's two separate clews. On boats larger than around thirty feet, the spinnaker will also be fitted with guys, which are similar to sheets but control the pole instead of the sail. On smaller boats the lazy sheet is ...
