Topping Lift

To avoid snagging the mainsail on the Lazy Jacks when raising sail, the boat

must be equipped with a topping lift or vang that holds boom lifted.

Altering Sail Cover

Take your sail cover to a sailmaker to have slits cut in the cover for the Lazy Jacks.

Slits should have Velcro or snap closures to make it easy to cover the mainsail.

Mark your cover after installation so the slots can be positioned correctly.

Determining the Location of Mast Tang

Measure the mainsail luff length or find the “P” dimension of the mast. Find this

measurement in the left column below and circle the number in the right column.

See drawing, page 3.
