Mainsail Stacking Systems

The Kemp Sails - Packaway

It is many years since Kemp Sails first introduced the Packaway mainsail stacking system. Proof of its success can be seen in any marina in the country, with many manufacturers emulating the principle.

 The system works in conjunction with lazyjacks to enable the mainsail to be lowered quickly, safely and efficiently. In partnership with slab-reefing, the Packaway provides a simple and effective reefing system, keeping the spare bunt of sail out of the cockpit and the helmsman’s line of sight.When not in use, the integral tie-down straps can be used to reduce windage. When it’s time to stow the main, all you need to do is pull the zipper to enclose the sail and protect it from the elements, ready to hoist at a moment’s notice. ImageThe Packaway works well with conventional mainsails but really comes into its own when combined with a fully battened main or Kemp Power Main.We will be happy to advise on the merits of converting your sail. (Please refer to the pros and cons of a fully battened mainsail).

The Packaway is supplied complete with Boot cover, Lazyjacks and mast turning blocks (see diagram). Easy to fit Collects the sail Produced in u/v stabilized acrylic Keeps mainsail above sight line Custom made to suit your boat Protects mainsail from the elements Tie-down straps reduce windage when not in use.

Fitting Instructions

The Kemp Packaway is designed to fit around the bolt rope at the foot of your mainsail as shown in the diagram (right). It is not attached to either the sail or the boom.

This is best achieved by removing the sail, centering the Packaway on the bolt rope and re-inserting the boltrope with the Packaway wrapped around it into the boom foot-groove.

Once the Packaway is in position, attach the tack and clew of the sail as normal.The Packaway is then suspended by attaching the lazyjacks to the webbing eyes.

Lazyjacks Installation

The Packaway will have three or four attachment points, depending on the length of the boom. Either way the lazyjacks will culminate in a single line which will travel to a turning block attached to the mast and back down to a cleat on the mast.The turning block should be popriveted to the mast at approximately 65% of its height. (High aspect mainsails can have the block fitted slightly lower, low aspect sails slightly higher.) To save damaging halyards and cables inside the mast mark the drill bit with tape to regulate the depth drilled. Any reefing pennants will need to be reefed through the slot in the foot of the Packaway, secured around the boom as before, with the slot adjusted using the double zip arrangement.

The boot at the forward end of the boom is fitted when the sail is not in use, and can be quickly secured using the hook and line arrangement and the adjustable mast collar.
