This single line reefing kit allows reefing control lines to be led aft to the safety of the cockpit. The system makes reefing your mainsail a quick and easy operation. Just lower the sail to a pre-determined mark on the halyard, tension the reefing line and trim the sail – all from the cockpit.

1 x Reefing slide on 25mm 'T' track with end fittings (No.1)
|Drill Bits & Taps
3.3mm Drill (to use in conjunction Electric Drill with 4 mm tap)
4.2mm Drill (to use in conjunction Tape Measure with 4mm tap)
Positioning the Reefing Slide on The Track (No 1)
Decide whether to place the track on the port or starboard side of the boom.
Remove track, drill using 4.2mm drill and tap using 5mm tap then secure in position using 5mm machine screw
Positioning of the Reefing Slide
Position the slide on the track ensuring the plunger end of the slide is aft and the becket on the slide is facing down. (This may need to be adjusted depending on whether it is fitted on port or starboard side of the boom. The eye will rotate but may require the use of pliers to carry out this operation). The position of the slide on the track can be adjusted during a sail trial.
The two plastic end caps can now be fitted ensuring they locate over the end of the track. (This is a push fit) Use the centre punch to mark position then remove before drilling and tapping as previously stated.
| Installing the Tang Block (No 3)
This should be installed on the same side of the boom as the track positioned on the mast so that the line pulls down and forward at 45º when reefed. If fitting two systems this position may vary Using the tang as a template, drill and tap as previously stated then secure using the 5mm pan head machine screws and washers provided. After securing, the screws can be removed and the surplus length inside the boom cut off, to prevent possible snagging of internal control lines on the sharp ends of the screws.
Installing the Bullseye (No4)
Installing Boom Eye Straps (No2)
Attach a line around the sheave on the Slide and the Tang Block, measure 1/3 of the length between the slider and the Tang Block. This determines the position of the first Eye Strap. Ensure the Eye Strap is positioned so the reefing line runs directly through it to minimise friction. Use the Eye Strap as a template for drilling both 5mm holes then rivet using pop rivets provided. Repeat the process for the other eye strap at the next 1/3 intereval.
Installing Stand Up Block
Use the Stand Up Block as a template and mark the four fixing holes. Remove block prior to drilling 4 x 5mm holes. 5mm counter sink stainless bolts are required for fixing down the Stand Up Block. These are not provided as deck thickness etc. may vary. To attain spread of the load, use a pad or penny washers on the underside. When fitting the Stand Up Block, use a high quality marine sealant to provide a durable water seal.
Reeving the Line
The line starts by being tied or spliced to the becket on the bottom of the slide (1) under the boom, up through the eye, down through the sheave on the slide, then through the two Eye Straps (2) on the boom, around the sheave of the Tang Block (3), up through the eye on the sail, down the other side through the Bullseyes, to the Stand Up Block, then off to the Deck Organiser.
Safety: Never set a sail whilst the craft is out of the water. When at dockside only raise the mainsail when the conditions allow, ensuring that the craft is securely tied and there is no possibility of a gybe.
Lower the main halyard to the correct position for reefing and reef mainsail. If correct, mark the halyard at the position of the cleat with permanent marker.
