Harken 430 Single Line Reefing - Manual (Page 7)

Step 7 Reeving the Control Line
General Instructions Detailed Instructions
A. Hoist the mainsail.
B. Starting at the eyestrap at the clew slider reeve the
line through the sail and blocks.
A. Adjust the clew car to find optimum sail shape.
Mark halyard.
Step 8 Adjust Clew Car
General Instructions Detailed Instructions
A. With the sail raised, move the clew slider to find the
optimum sail shape. Try reefing the system. The clew
line should pull down and aft at a 30 to 45° angle. It
is important to have a topping lift when reefing to pre-
vent the boom from dropping down into the boat when
the halyard is eased.
Reefing Tip – Marking the Halyard
Mark the halyard so you know how far to ease it when lowering
the main in preparation for reefing. Start with the sail reefed and
the halyard tensioned. Mark the halyard at the cleat using a per-
manent marker. When reefing the sail, set the topping life, lower
the halyard to the mark and pull the reef line, and tension the
halyard if necessary.
A. To reef, set the topping lift, ease the halyard, pull the
reef line, and tension the halyard if necessary. Test the
system before you need to use it.
Step 9 Reef
General Instructions Detailed Instructions
A. Make sure the topping lift is set. Ease the halyard to
the mark that you have made and cleat it. Pull the reef
line until the clew and tack are down near the boom.
Keep pulling until the foot of the sail is tight and cleat
the reefing line. Check to make sure you can lower
slugs far enough to reef. Do not use stop above feeder
gap. Mount feeder plates so slugs pass below feeder.
Feeder plates are available from spar makers and are
screwed into the mast on either side of the feeder.
Topping Lift
B. You need to supply 5/16” (8 mm) double braided
Dacron line in a length as determined in the formula
on page 2:
1) Tie or splice line end to eyestrap on clew slider.
2) With sail hoisted, run line under the boom and up
through reefing grommet at clew.
3) Lead down through the block on clew slider.
4) Run line forward through eyestrap on boom.
5) Lead line up through big bullet block on mast.
6) Then up through the reefing tack grommet.
7) Down through bullseye on other side of mast.
8) Through the mast base big bullet block.
9) Through deflector block.
10) Back to cleat.
