You are here:Home > Performance line
Our 'Performance lines' are aimed at the performance oriented cruiser and club racing boats. The advantage of this line are there superior breaking strength, which gives less halyards and sheets stretch, thereby maintaining the desired sail shape without having to constantly adjust the line tension. This also usually allows us to drop on diameter size considerably reducing the overall halyard weight hereby improving initial stability. Typically these lines have a polyester cover and there cores are often a blend of hi-tec and regular fibers. Southern Ropes SuperSpeed braid has a HMPE (high modules polyethylene - often know by the trade names Spectra or Dyneema) core and durable 24 plait polyester cover.
