Harken recommends equipping jib reefing and furling systems with lead blocks for safe furling from the cockpit. Lightweight, UV-stabilized Carbo blocks run exclusively on ball bearings for fast trimming under any load. Furling leads are offered separately or in complete kits. Harken offers halyard restrainers that install on the mast near the top of the foil to keep the line against the mast, preventing halyard wrap when furling. Also available are stanchion-mount bases for Carbo and Classic blocks, as well prefeeders and snap shackles to facilitate fast sail changes.
