Dinghy Polytech is a high-end crossover product for high performance dinghies.
The ultimate dinghy product with Dyneema® SK78 for the highest demands.
The ideal choice for minimal stretch and creep, coupled with minimal weight.
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®
