This range of standard pre-made jib sheets has been designed to make replacing sail sheets on your boat quick and simple. They come in three standard colours: grey, navy blue and red. This is a performance specification for a jib sheet made from Gottifredi Maffioli Powertech, which has an SK78 Dyneema® core with a polyester/Tecnora cover, for extra grip and durability on the winch. At the cockpit end, it is finished with a Flemish eye and at the working end it has a covered eye splice plus a soft shackle, for connection to the clew of your sail. This 10mm diameter x 12m long sheet is recommended for use as a jib sheet on sail boats between 34 – 39 ft. However, due to variations in sail sizes and cockpit setups, we suggest you double check the appropriate length for your own boat. We use the following formulae for jib sheet length: 1 * Boat Length (LOA) It is better to have a sheet 1-2 m too long than too short! N.B. Diameter recommendations are based on a medium displacement monohull. For heavy displacement boats and catamarans, you may need to go up a size in rope diameter.
