Polyester double braided rope. Low stretch with high tensile and dielectric strength. Meets or exceeds US Military Specification MIL-DTL24677B. Specific gravity 1.38.

This is not New England Ropes brand line but it does not cost as much either. it is good double "yacht" braid - the stuff that stays flexible and is easy on the hands. It is hard to find it outside a chandlery or rigger's supply store.

Polyester rope stretches much less than Nylon and is preferred for halyards and outhauls - anything you want to stay put rather than stretch over time. It will not stretch when wet as Nylon will.

Double Braid: A braided cover surrounding a braided core, producing a rope designed for strength, durability, shape and easy handling. For use in running rigging and dock lines.

Lbs per 100' (2) Min Breaking Load in lbs. (3) Working Load Ratio (4)
1/4" 6 1.95 1,315 5-12 to 1
5/16" 8 3.05 2,050 5-12 to 1
3/8" 10 4.35 2,900 5-12 to 1
  1. Diameter is approximate and is actually determined by linear density. (Pounds per 100')
  2. Linear Density is considered average weight per 100'. Tolerances: 3/16" - 5/16" diameters inclusive +plus or -minus 10%; 3/8" - 9/16" inclusive +plus or -minus 18%; and 5/8" and up +plus or -minus 5%.
  3. New rope Minimum Breaking Strength is based on data from a number of manufacturers and represents a value of 2 standard deviations below the mean, established by regression analysis.
  4. For critical applications where life or limb of Dynamic Loading is present, use the higher ration division. Example: 10 000 pounds 12 = 833 pounds working load ratio
