Mainsheet ZS75 red  6mm for the Optimist -7 metres - Southern Ropes designed this new mainsheet with the help of Paul Goodison. The rope has a treated and heat set Dyneema braided core with a blended cover of high tenacity spun and continuous filament polyester to create a very grippy and soft rope. The rope runs through the blocks very easily and its unique grip makes using this 6.0mm rope very manageable in strong wind conditions
