Designed for the little One Design, the Power3 ratchet blocks offer three holding power options suitable for a wide variety of regatta conditions. This choice translates for sailors into finer adjustments in association with the hoist, which guarantees them an ideal level of power, responsiveness and control. The patented Harken T2 Ratchamatic pulleys combine the design of the T2 models with a threading fixing system. Featuring fiber-reinforced composite material cheeks, an aluminum sheave and a ratchet mechanism with a reduced number of moving parts, these lightweight pulleys are extremely durable. Fixing by threading allows them to be placed flush with the deck. In the case of using a large diameter rope to make a splice, the end of the rope can also be used to position these pulleys at the desired height for perfect alignment. Under the effect of the pressure exerted on the rope, the pulley mechanism automatically switches from free rotation mode to ratchet mode. The mainsail and jib sheets can thus move freely when a buoy passes, while the asymmetrical spinnaker is instantly shocked when gybing. The cheeks of the T2 Ratchamatic blocks have a large arrow which clearly indicates the direction of the rope. To be used for adjusting the mainsail and spinnaker sheets of sports catamarans, dinghies and regatta sailboats. These pulleys are delivered with Spectra® rope.
