Lazy Jack Systems

These kits contain everything for installing a simple, variable system

Keep your mainsail under control and on the boom as it’s lowered. Works exceptionally well with fully-battened mains, but can also be used with conventional sails. Everything you need to install a simple, adjustable system is included in the kit: pre-swaged wires, blocks, eyestraps, line, a cleat, fasteners and instructions (including how to alter your sail cover for use with lazy jacks).
