Checking the Tasar Rig

Checking the Tasar Rig

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 -

  1 (Top) 4.6 lbs 2.1 kg
  2 4.1 1.85
  3 4.1 1.85
  4 2.9 1.3
  5, 6 and 7 Irrelevant

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.
