Spreader Patch
A spreader patch is a fabric reinforcement at a point on a sail where it is likely to rub with the spreader on a mast. Use and construction Spreader patches may be placed on a jib, when it overlaps with the mast, or on the mainsail, where it may interfere when furled, or when the sail is backwinded against the mast. Patches may be made of tape, sticky-backed Dacron Polyethylene terephthalate (or poly(ethylene terephthalate), PET, PETE, or the obsolete PETP or PET-P), is the most common thermoplastic polymer resin of the polyester family and is used in fibres for clothing, containers for liquids and foods ..., or other material that is compatible with the type of sailcloth being reinforced. When applying such patches, it's important to affix it starting from the inner part of the sail, towards the edge of the sail (leech).

Spreader (sailboat)
A spreader is a spar on a sailing boat used to deflect the shrouds to allow them to better support the mast. The spreader or spreaders serve much the same purpose as the crosstrees and tops in a traditional sailing vessel. Spreaders are used to increase the angle between the rigging and the mast, providing better support, and to adjust the mast's shape and bend. This allows the mast and rigging to be lighter and thinner, reducing their total weight. Spreaders may be made of metal, often aluminium; wood, often spruce; or composite material such as carbon fiber. Spreader design and tuning can be quite complex. The spreaders may be fixed (rigid) or swinging (pivoted at the mast). Most cruising boats have fixed spreaders, but swinging spreaders are found on some racing boats. The length of a boat's beam determines how long the spreaders may be, so some boats have multiple sets of spreaders so the shroud can reach the desired angle from the mast. Boats with tall masts, such as r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Mainsail
A mainsail is a sail rigged on the main mast (sailing), mast of a sailing vessel. * On a square rigged vessel, it is the lowest and largest sail on the main mast. * On a fore-and-aft rigged vessel, it is the sail rigged aft of the main mast. The sail's foot is normally attached to a Boom (sailing), boom. (In extremely heavy weather, the mainsail may be lowered, and a much smaller trysail hoisted in its place). Historical fore-and-aft rigs used a four-sided gaff rigged mainsail, sometimes setting a gaff topsail above it. Whereas once the mainsail was typically the largest sail, today the mainsail may be smaller than the jib or genoa; G. Prout & Sons, Prout Catamaran#History, catamarans typically have a Mast-aft rig, mainmast stepped further aft than in a standard sloop, so that the mainsail is much smaller than the foresail. Bermuda rig The modern Bermuda rig uses a triangular mainsail aft of the mast, closely coordinated with a jib for sailing upwind. A large overlapping ...

Furl
Furl (from File Uniform Resource Locators) was a free social bookmarking website that allowed members to store searchable copies of webpages and share them with others. Every member received 5 gigabytes of storage space. The site was founded by Mike Giles in 2003 and purchased by LookSmart in September 2004. Diigo (a web annotation, social bookmarking & research tool website) bought it from LookSmart in exchange for equity. Features Furl enabled members to bookmark, annotate, and share web pages. ''Topics'' were used to categorize saved sites, similar to the tagging feature of other social websites. Additionally, a user could write comments, save clippings, assign each bookmark a rating and keywords (which are given greater weight while searching), and have an option of private or public storage for each topic or item archived. Considered one of its main features, Furl also privately archived a complete copy of the HTML of each page that a user bookmarks, making it accessible ...

Mast (sailing)
The mast of a sailing vessel is a tall spar, or arrangement of spars, erected more or less vertically on the median 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. Large ships have several masts, with the size and configuration depending on the style of ship. Nearly all sailing masts are guyed. Until the mid-19th century, all vessels' masts were made of wood formed from a single or several pieces of timber which typically consisted of the trunk of a conifer tree. From the 16th century, vessels were often built of a size requiring masts taller and thicker than from single tree trunks. On these larger vessels, to achieve the required height, the masts were built from up to four sections (also called masts). From lowest to highest, these were called: lower, top, topgallant, and royal masts. Giving the lower section ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Dacron
Polyethylene terephthalate (or poly(ethylene terephthalate), PET, PETE, or the obsolete PETP or PET-P), is the most common thermoplastic polymer resin of the polyester family and is used in fibres for clothing, containers for liquids and foods, and thermoforming for manufacturing, and in combination with glass fibre for engineering resins. In 2016, annual production of PET was 56 million tons. The biggest application is in fibres (in excess of 60%), with bottle production accounting for about 30% of global demand. In the context of textile applications, PET is referred to by its common name, polyester, whereas the acronym ''PET'' is generally used in relation to packaging. PET used in non-fiber applications (i.e. for packaging) makes up about 6% of world polymer production by mass. Accounting for the >60% fraction of polyethylene terephthalate produced for use as polyester fibers, PET is the fourth-most-produced polymer after polyethylene (PE), polypropylene (PP) and polyvinyl ...
