This highly sought after dinghy racing line combines all the features required of high-performance ropes. It is constructed as a 12-strand, single-braid, hollow-fiber plait, made of a blend of impregnated nylon and Dyneema™ SK75.
These materials make the rope extremely abrasion-resistant and with low stretch.
The sheet is easy to grip, even when wet, and is easy to splice.
• Hollow-fiber plait
• Extremely abrasion resistant
• Extremely low stretch
• Does not absorb any water
Heavy on the technical side...
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.
Of particular interest these days is the difference between Dyneema SK75 and SK78. Dyneema SK78 has the same high strength of SK75, but with lower creep (non-recoverable stretch).
Honeywell International produces a similar UHMWPE fiber, marketed as Spectra®
