Mainsheet Fine Tune Line for the J/105. The Fine Tune Line is the secondary line in the mainsheet trimming system, designed for making smaller adjustments to the trim. We use 8mm Alpha Ropes SSR, a single braid blend of Spectra and Cordura makes this line both durable and soft in the hand. Very similar to Maffiloli switfcord. Cut Recommend length of 30 feet with an eye splice on one end for attaching to the becket on the block and an end whip on the other. A great upgrade for any J/105 sailors!
