Dinghy Control, Blue - 4 mm

Dinghy Control is a high tech, small boat racing line, perfect for lightweight controls and sheets.
Diolen PES (polyester) is used for the cover, and Dyneema® SK78 for the core.

The cover can be stripped and tapered, where needed, to save weight and decrease diameter.
The unique SYIS polyurethane treated core (on sizes 4mm and larger), has excellent UV and abraision resistance.

This line is ideal for critical load applications such as halyards, backstays and spinnaker sheets.

• Diolen polyester cover with a durable 32 plait "one over one" single strand weave provides abrasion resistance and excellent cover/core grip
• 12-Strand Dyneema SK75 braid core
• On sizes 4mm and larger the core is impregnated with a unique, lightweight SYIS polyurethane treatment, where each individual thread is fully coated
• Just 0.6% stretch at 15% of average breaking strength


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®
