What To Wear Guides – Apparel Guides for Sailing | West Coast Sailing


Spectra and Vectran line have extremely low stretch and are perfect for operation applications such as travelers or as part on a control set up .

Dyneema, Spectra & Vectran Sailing Line

If you ‘re looking for line with about zero reach, then our choice of Dyneema, Spectra, and Vectran lines are for you ! These high technical school lines have near zero stretch and perfective for performance applications such as travelers or as depart on a control set up. These lines are uncover and more likely to wear, but do feature UV coating to protect from sun wrong .

Low Stretch Lines Explained

Dyneema & Spectra

Dynema® and Spectra® are made from UHMWPE ( Ultra High Molecular Weight PolyEthylene ), a long chain, high lastingness, oriented maroon, synthetic fiber with identical high strength and high grinding electric resistance. This fiber is besides known as HMPE ( High Modulus PolyEthylene ). Dynema® is the dutch company DSM Dyneema ‘s brand of UHMWPE, used by Samson in their Amsteel and Amsteel-Blue dyneema lines. Honeywell International produces a like UHMWPE fiber, marketed as Spectra®. Both Dyneema ( Dynema ) and Spectra offer closely identical characteristics are can be used interchangeably in sailing applications, depending on where you reservoir your trace.

Vectran

Made from a LCP ( liquid quartz glass polymer ) fiber, Vectran exhibits high military capability, excellent crawl and abrasion resistance, excellent flex/fold and chemical resistance, and great heating system and cut resistance. Vectran is an alternative to Dyneema or Spectra and less stretch and creep. many think Vectran is the ultimate roughage, though it does not have quite the fatigue life or UV resistance of Dyneema or Spectra. besides it is a little heavier and will not float .

Common Applications

Dyneema, Spectra, and Vectran lines are commend for use in applications where low to zero stretch is the core necessity. It ‘s park to see these lines used as halyards, in sail control line systems, as travelers, or even as replacements for wire rig in some operation applications. Since most first gear reach Dyneema, Spectra, and Vectran lines are a single-braid without a shroud, they are not recommended for applications where the line needs to be cleated and uncleated frequently. In those consumption cases you ‘ll want to consider a line with a cover, such as a high operation dyneema or spectrum kernel line with a clayey duty polyester cover charge .

Finding The Right Diameter

If you are replacing an existing line, the easiest direction to determine what diameter you need is to match what you already have. This can be done with a caliper or by close estimate with a tape measure. If you ‘ve previously used a 7mm sheet and it has performed well, another 7mm line is probable a great choice. In most applications, there is some flexibility in the claim diameter that can be used. Most blocks, for example, have an ‘ideal ‘ diameter ( internet explorer, the line diameter that runs most effectively though the block ‘s sheave ) but besides have a range so that you can run a slenderly thin or slenderly thicker line. If you have a sheet that is getting hung up in your rig, stepping down 1-2mm might help the sheet run more efficiently. If you have a larger boat or carriage and want to run a thin sheet, consider a double braid note that features a Dyneema or spectra core for persuasiveness .

Line Diameter Conversion

1mm = 3/64 inch | 2mm = 5/64 edge | 3mm = 1/8 edge
4mm = 5/32 inch | 5mm = 3/16 column inch | 6mm = 1/4 inch

7mm = 9/32 column inch | 8mm = 5/16 edge | 9mm = 3/8 inch
10mm = 25/64 in | 11mm = 7/16 in | 12mm = 1/2 in

Double Braid vs Single Braid

Two terms you will often see in line descriptions are ‘double braid ‘ and ‘single braid ‘, which refer to the way the line is constructed. At the most basic level, a double braid wrinkle has a binding and a core whereas a individual braid does not, but there are other important distinctions to consider when making a line choice .
Single Braids are made up of either 8 or 12 strands that are braided into a circular form, half clockwise and one-half antagonistic clockwise. This produces a line that is lissome, absorb twists, and tends not to kink. There are two types of one braid lines : operation one braids and polyester/blended single braids. Performance single braids are made from fibers with very low load and designed to handle extreme loads – think Dyneema, Spectra, or Vectran. Polyester/blended individual braids, sometimes called hollow braid, are easy and easy to grip, built for sheets and hand-adjusted control lines. These are less park than performance unmarried braid lines but recommended in a few specific applications.

The Dyneema, Spectra, and Vectran lines on this page are Single Braids.  The exception is the Robline Dinghy Vectran, which has a Vectran core .
Double Braids, sometimes called braid on braid, have a braided core within a braided outer jacket or cover. This creates a firm, durable, smooth-running lineage that is easy to handle. double braids are used for the huge majority of all running rigging on sailboats including sheets, halyards and control condition lines for both cruising or racing. There are two types to consider : polyester bivalent braids and high-tech doubling braids. Polyester double braids, found most normally on recreational and cruising sailboats, have a polyester overlay with polyester kernel. These are low maintenance, low-cost, and durable, while offering relatively low stretch and high working loads. For extra strength and minimal stretch, consider high-tech duplicate braids. These lines typically feature a Dyneema or Spectra core ( non-stretch ) inside a polyester or polyester/dyneema blend cover for extra lastingness. They are more expensive but often the go to choice for high performance racing boats .
