Boom: The outhaul is assembled at Sparcraft and is delivered in rigged configuration.
Messenger lines are provided if you wish to run the reef lines.
After the mast is stepped attach the boom at the gooseneck and attach the mainsheet
block and vang blocks to the boom and mast attachment points.
Lifelines/Stanchions: Insert stanchions tubes into the bases and tighten the Phillips
head screws. To prevent the screws from vibrating loose during trailering or heavy air
sailing, dip the screw ends in silicone or spray them with blue Loctite before tightening.
To connect lifelines: attach the fork fitting to the eye on the bow pulpit (with pin inserted
outboard to prevent jib from catching on ring ding), then unscrew the stainless loop at
the opposite end of the lifeline, and reeve the stud aft through the stanchion tops. Then
reattach the stainless loop and secure to the stern pulpit with the rope lanyard provided.
Tiller Extension: The J/80 is provided with a tiller extension. This extension is included
in the rigging box with the boat and requires installation by the dealer or owner. Follow
the directions included with the extension and locate to suit. We recommend locating
this at least 4” behind the forward end of the tiller to ensure space to directly control the
tiller with your hand.
Rigging the Bow Sprit: Lead the tail of the pole control line through the inboard hole at
the back end of the sprit and tie a stopper knot. Then run the line through the Harken
single block on the forepeak bulkhead and lead it aft through the plastic eyes on the
overhead to the cleat at the back of the cabin trunk. IMPORTANT: Tie a stopper knot
aft of the cleat to prevent the back end of the pole from hitting the main bulkhead when
the line is released.
Roller Furler: Your J/80 is equipped with a Harken Roller Furler attached to a dyform
wire rigging headstay. The furler line leads aft from the furler through a centerline bow
eye then aft to port, cleating at the side of the cabin in the cockpit. After attaching the jib
head and tack to the furler shackles, be sure to tape the shackles.
Tuning the Rig
Your sailmaker will have specific rig tension recommended for different conditions.
We'll stick with the basics to obtaining a well-tuned J/80.
Before Stepping the Mast:
• Measure the headstay length- this should be approx. 32'11" from pin to pin.
Consult your sailmaker for the recommended length for your sails.
• Install an optional Windex to top of mast - We suggest setting each Windex tab to
30 degrees off center.
• Tape spreader ends and all exposed pins
• Run a short piece of line between the upper shroud (about 6” above the bottom
spreader) and the intermediate shroud. Then tape off. This helps prevent the
spinnaker from catching in the triangle formed by the spreader and the two shrouds.
• Add the mast boot
