HARKEN
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).

  • Small Boat Boom Length: 7' to 13' (2.13m–3.96m); mainsail luff length: 21' to 32' (6.4m–9.75m)
  • Medium Boat Boom Length: 10.6' to 16' (3.2m–4.87m); mainsail luff length: 32' to 42' (9.75m–12.8m)
  • Large Boat Boom Length: 12' to 16'. (3.7m–4.9m); mainsail luff length: 35'7" to 48' (10.88m–14.63m)

Includes pre-swaged vinyl-coated stainless cable, ball-bearing blocks, eyestraps, line, a cleat, fasteners, and pictorial instructions.
