J/109 OWNER GUIDE

Rudder Stock Stuffing Box: is located at the top of the fiberglass rudder tube beneath the decks. It
is a simple design that prevents water from entering the hull. A stainless sleeve bearing surface
surrounds the rudder shaft at the point where a rubber seal is forced against it to prevent water from
rising up the tube.
Emergency Tiller: is operated by lifting off the access plate (amidships), and placing the base of the
tiller over the head of the rudder stock. Rudder is rotated using the T-shaped handlebars. Fit the
emergency tiller NOW to see how the system works BEFORE you get caught in a situation where you
won’t have the time!
J/109 Rigging
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 and for a racing crew.
The most unique system on your J/109 is the bow sprit system for the asymmetric spinnaker. We
believe this system is a major improvement over conventional systems and so let's start by explaining
how it works.
•
Carbon Fiber Bow Sprit: The carbon fiber bow sprit is custom made by Advanced Composites and
is designed to withstand the loads associated with the asymmetric spinnaker without any additional
support. The pole consists of a carbon tube finished with two molded end fittings. The forward
end fitting has a "U" bolt which serves as the attachment point for the tackline 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 bowsprit is designed to be adjusted
without leaving the cockpit. The line is dead-ended to the inboard 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 outboard padeye on the forepeak bulkhead, then through the stainless handrail in
the main salon, through the head, and finally to a cam cleat mounted on the aft side of the cabin
top to starboard.
•
Harken Headsail Furling: A standard Harken Furler is provided with the boat and requires assembly
prior to installing the mast. A complete instruction manual is included with this hardware detailing
the procedure. The pin-to-pin headstay length necessary to complete this task for the J/109 is
14700mm or 48’2-7/8”.
•
Mast: Rigging the J/109 mast is a common procedure, and best handled by a qualified marine
rigger. All spreaders, shrouds, and halyards are installed and properly taped and secured. The
masthead anchor light and the steaming light are shipped loose with the J/109 Sparcraft mast to
prevent damage during shipping. Be sure these and all other mast related electronics and wind
indicators are properly wired and installed prior to stepping the mast. After stepping the mast it is
VERY IMPORTANT to install the wire fitting from the forward face of the mast in the interior up to
the underside of the deck and tighten prior to going sailing. We also recommend that a small cord
is tied and taped approx. 24” above each lower spreader between the intermediate shroud and
upper shroud. Simply tie this line to each shroud (allowing for some slack) and tape ends over with
rigging tape. This prevents the asymmetrical spinnaker (during a take down) from potentially
dropping into the V that is formed at the lower spreader between these shrouds.
•
Hydraulic Backstay: The J/109 is equipped with an integral hydraulic backstay to help you fine
tune your rig and sails for optimum performance. This hydraulic unit is simple to operate, easy to
maintain, and highly reliable. The cylinder is affixed at its lower end to a stainless backstay
