Based on Robline’s exclusive STS Technology (STS = Stronger than Steel) and the well-proven Dinghy Star Ultra - cover with PBO, this product helps you to keep your desired rope tension exactly to the point needed. There is nothing left in terms of stretch, constructional stretch, and abrasion resistance. Dinghy Star Pro Ultra is best used where the smallest possible change to the desired settings while sailing is needed. It is the solution when very high loads meet the request for the smallest possible diameter to reduce windage and weight. It has been tested and used as a Nacra17 tack line and Gennaker halyard. It replaces bigger diameters of SK99-based controls.
