Emergency Tiller -­‐ is installed by removing the access plate, and placing the base of the tiller over
the head of the rudder stock. Fit the emergency tiller NOW to see how the system works BEFORE
you get caught in a situation where you may not have time!
Before Launching -­‐ check the system of cables, quadrant, and sheaves to ensure they are working
smoothly. If the steering seems loose, tighten the turnbuckles by hand and re-­‐pin them. Beware
that you do not over-­‐tighten the cables. Please note that your steering should be checked
periodically for "tightness" and for presence of properly bent cotter-­‐pins.
Rigging Systems
The running and standing rigging items supplied with your boat are designed for efficiency. A
wealth of racing and cruising experience has gone into the deck layout to make sailing and boat
handling safe and easy to handle by a couple or a racing crew.
The most unique system on your J/105 is the bow sprit system for the asymmetric spinnaker.
We believe this system is a major improvement over conventional systems, so let's start by
explaining how it works!
Carbon Fiber Bow Sprit -­‐ The carbon fiber bow sprit is custom made and is designed to withstand
the loads associated with the class asymmetric spinnaker without any additional support. The
pole consists of a carbon tube faired smooth and finished with a clear Awlgrip high gloss paint,
and two end fittings. The forward end fitting has a "U" bolt which serves as the attachment point
for the tackline/snuffer block. The aft end fitting houses all hardware necessary for the adjuster
line and shock cord retrieval system.
Bow Sprit Launching Line -­‐ The control line to pull out the bow sprit is designed to be adjusted
without leaving the cockpit. The line is dead-­‐ended to the outboard pad eye on the forward most
bulkhead in the forepeak. The line then leads through the thru-­‐pole blocks on the aft end fitting
of the carbon fiber pole (be sure the "U" bolt on the other end of the pole is up), forward through
a block on the inboard padeye on the forepeak bulkhead, then under deck through the bullseye
fairleads, the main bulkhead, and finally to the cam cleat mounted on the aft side of the cabin top
to starboard
Asymmetric Shock Cord Retrieval System -­‐ The shock cord system allows the pole to automatically
retract when you uncleat the control line. Set up as follows: attach one end of shock cord to the
pole end fitting pad eye, lead through the Harken double block mounted on padeye on the
hanging locker bulkhead, then lead cord through the bullseye on the bottom of the pole end
fitting to the forward single Harken block, back through the bullseye, around the becket of the aft
block, and secured to the back end of the pole. You may need to experiment once or twice to get
the appropriate tension on the shock cord. It should be relatively easy to extend the pole fully,
and when released, should quickly retract into the boat. If you do not already have a preventer
line, put a knot in the cockpit control line behind the cam cleat (in the cockpit) to prevent the
sprit from banging into the bulkhead when released.
Harken Headsail Furling -­‐ The Harken Unit 1 furler is provided with the boat standard and
requires assembly prior to installing the mast. A complete instruction manual is included with
this hardware detailing the proper procedure. The pin-­‐to-­‐pin headstay length necessary to
complete this task for the J/105 is 12929mm or 42’ 5”. The provided pre-­‐feeder should be lashed
and taped halfway between the feeder gate and the lower extrusion leg.
