3/8" (9.5 mm) Lightning Rope - Blue (18,500 lb)

Lightning Rope, a 12-strand single braid, is a reliable lightweight line with high strength, very low stretch, and no creep.
It is great for use where static loads are anticipated and weight is an issue — as in competition grade running rigging.

The Samthane™ coating is abrasion resistant, and has different formulations for specific rope fiber types.
The Samthane coating adds firmness and greatly improves wear life.
It also enhances abrasion resistance, reduces cutting and snagging, and helps prevent contamination.

• Lightning is Samson's lowest stretch rope
• Does not creep (stretch under high static loads) - making it ideal for halyards, trapeze lines, and leech lines on larger vessels, etc.
• Elongation when loaded at 30% of breaking strength is only 3/4 of 1%
• Constructed from a blend of Vectran® and Dyneema® SK-75 HMPE (high molecular weight polyethylene) fibers
• 12-Strand hollow braid construction
• Supple, absorbs twist, and resists kinking
• Splicing technique: full-bury 12-strand splice
• Strengths in specification table are for spliced lines
• Sold by the foot


Heavy on the technical side...

The only LCP (liquid crystal polymer) fiber available, Vectran exhibits high strength, excellent creep and abrasion resistance, excellent flex/fold and chemical resistance, and outstanding heat and cut resistance.

Dynema® is the Dutch company DSM Dyneema's brand of UHMWPE (Ultra High Molecular Weight PolyEthylene fiber), a long chain, high strength, oriented strand, synthetic fiber with very high strength as well as high abrasion resistance.
This fiber is also known as HMPE (High Modulus PolyEthylene).
Dyneema is available in a number of formulations, SK-60, SK-75, SK-78, SK-90, etc. Each progressively stronger and more expensive.

Honeywell International produces a similar UHMWPE fiber, marketed as Spectra®
