1. Fit the lower furler to the bottom of the forestay; attach the boss of the furler to the stemhead fitting with an RF616 shackle. Fit the upper furler to the top of the forestay; put an RF616 shackle into the boss. Fit the jibsheets to the middle hole in the clewboard.

2. Assemble the mast;- fit the vang, the downhaul, the topmast with halyard and fall, the wind indicator. Lay the mast on the boat, butt forward.

3. Check that a 1" x 3/8 x 1/16 nylon mast step washer is in place on the mast step.

4. Attach the shrouds and upper jib furler to the hounds with the ¼" bow shackle. The RF616 shackle into the upper furler lies between the shroud thimbles. Set the shroud adjusters "long".

5. Shackle one adjuster to one stay slide.

6 Have an assistant hold the free shroud lightly, erect the mast and place the butt on the mast step pin. Shackle the other shroud to its stay slide.

7. Reeve the jib luff downhaul lightly through the lower forestay thimble, and furl the jib.

8. Close the shroud adjusters symmetrically until the shrouds are just taut with both stay slides fully forward.

9. Lap in the stay slides. Use mineral oil, or valve lapping compound, and work the slides under increasing tension until full tension is applied (both slides fully back). Keep at it until the action is smooth. (Usually needs 50 to 100 strokes under full tension each side.) This exercise will usually bed the shrouds a little - re-set the adjusters to just taut with both slides fully forward. Clean up thoroughly. Any traces of residual oil will later soil the sails. Set the slides half back.

10. Unfurl the jib. Tension the luff downhaul to just eliminate horizontal wrinkles. Another way is to tighten until a vertical tension line shows down the luff, then ease until it vanishes. With a near-new jib both ways give the same tension. Never over-tighten.

11. Mark the jib sheets 6" (150mm) from the clewboard.

12. Check shape smooth. Check five sets of tufts. Trim tuft length where necessary so tuft cannot cling to thread of stitching.

14.  Batten the mainsail. If not using factory-supplied battens, the design Euler crippling loads are -

Batten Tension: Tension Nos 1, 2, 3 and 4 until tension creases just show along the batten pockets. Apply less tension to Nos 5 and 6, and little to No 7, otherwise it will adopt a reverse bend when running in very light air.
Hoist the mainsail. Apply no vang, downhaul nor mainsheet tension.
