This system is based on the typical Aussie Skiff Mainsheet System. It is commonly used on dinghies, skiffs and small sports boats, with a 3:1 end-boom purchase system. The blocks shown in the image are RF48109 x 3 and RF62175 x 1. Sailors of smaller boats may wish to substitute the RF48109’s for RF35101’s. The RF62175 can be substituted for RF62174 if the cleat is not desired. Smaller boats can use RF56101. The bridle can be constructed from Dyneema® such as Robline Ocean 3000 XG. An adjustable splice on each end (where it connects to the hull) is desirable so that the bridle height can be adjusted so that at max Vang and Cunningham the bridle is just block to block; this ensures the boom is on the centreline for height upwind. If possible, use a tapered mainsheet, which should be set up so that the “thin part” can’t ever go into the ratchet block when fully sheeted.
