Replacement halyard line. 3 mm Dyneema halyard with 2 spliced loops. This line can be weaved through the Harken blocks used on the Optimist rig.
This halyard line is made with Dyneema which is one of the strongest rope materials available. Dyneema has been specially developed to function as a low stretch line, with good UV resistance.
With spliced ends measured accurately, you will be able to fit this halyard line directly on to your mast, and not waste time setting up your halyard system before going sailing. This halyard line is compatible with a wide range of masts including all of the BlackGold Optimist Mast range.
