This range of standard pre-made halyards has been designed to make replacing halyards on your sailing boat quick and simple. They come in three standard colours: grey, navy blue and red. This is a basic specification for a 1:1 forward halyard (genoa / spinnaker) made from a durable double braid polyester Easycruise, from Italian rope makers Gottifredi Maffioli. At the cockpit end, it is finished with a Flemish eye (to simplify running halyards through the mast) and at the working end it has a covered eye splice plus a Ronstan snap shackle, for connection to your sail. This 8mm diameter x 25m long halyard is recommended for use on masts with an “I” measurement of between 8 – 10m. However, due to variations in cockpit setups, we suggest you double check the appropriate length for your own boat. We use the following formulae for 1:1 genoa / spinnaker halyard length: 2.1 * I (Isp) + [distance from mast to halyard winch] + 2m It is better to have a halyard 2-3m too long than too short! You can also extend the life of an over-length halyard by re-splicing it and running it in the opposite direction.
