small synthetic control lines found on high-tech dinghies.

captive grooved race and has a 250 lb (113 kg) safe working
load - the highest on the market compared to similarly
Dinghy control lines, Spinnaker pole trip lines, Big Boa t leech lines, Outhauls, Downhauls, Cunninghams, Traveler controls and Halyards on prams.
