single boom block, back down to the second block on the traveler car, and out to the other deck block and 
finally to the other winch. The system is designed to allow extremely easy adjustments of the mainsheet 
by any size or age person.  The self-tailing winch feature also facilitates single-handed sailing and rapid 
adjustments during sailing maneuvers.  Be sure to put a “stopper knot” at both ends of the sheet. 

Traveler:

 consists of a traveler track and traveler car mounted in the cockpit.  The car is controlled by a 

7:1 purchase system led to either side of the cockpit.  The traveler control line dead-ends outboard on the 
becket of the control block, then runs back and forth between the traveler car and end fitting, finishing at 
the “head-knocker” cleat assembly mounted just forward and outboard of the traveler track.  

Reef Lines:

 are designed to be fully functional from the cockpit.  The system includes a single line reef 

system and an additional clew & tack reef.  Please refer to the rigging diagram for details.  

Outhaul:

  is 18:1 internal tackle system pre-assembled by Hall Spars and cleated on the underside of the 

boom.  

Backstay:  

A Sailtec hydraulic backstay and vang adjusters are included with the J/145 to enable you to 

control the upwind shape of the mainsail by bending the mast and tensioning the leech of the main.  The 
pump and release valve on the two function panel mounted on forward face of pedestal in the cockpit 
control the operation.    

Jib/Genoa Controls 

Jib/Genoa Halyards: 

 exit the mast on the port and starboard sides of the mast and run through a turning 

block at the mast collar aft to the forward halyard winches.  (see Halyard Layout Diagram).    

Jib/Genoa Sheets:

  are attached to the headsail with large J-Lock shackles.  For a small jib, lead the 

sheet inboard of the shrouds, through the jib or genoa car on the track then aft to the primary winches.   If 
a large genoa is used, the sheets lead outboard of the shrouds and to then to the winch. The J/145 is 
equipped with two “stand-up” Harken blocks outboard of the cockpit.  These are designed to deflect the 
genoa sheet around the dodger when the dodger is rigged. 

Jib/Genoa Blocks & Tracks:

  are located port and starboard along the cabin sides.  Adjustable pin stop 

jib lead blocks are supplied for the forward in board & outboard tracks and can double as outboard cars 
for the genoa if necessary.  The genoa system is standard with a Harken adjustable system to allow fine 
adjustment while racing or under load.  

Spinnaker  Equipment 

Spinnaker Halyards:

 exit each side of the mast and lead through a turning block at the mast collar to the 

forward halyard winches to port and starboard.  

Spinnaker Sheets:

 attaches to the clew of the spinnaker with Tylaska T-12 shackles and leads aft 

outside the lifelines through the spinnaker sheet blocks (just in front of the stern pushpit), forward through 
the double foot blocks, then to either the cabin top or primary winches.  When hooking up the 
asymmetrical spinnaker the windward (or lazy) sheet should be led in front of the headstay. 

Tack Line: 

 The tack line leads from the spinnaker clew through a Harken 75mm block on the bow sprit 

and aft to a rope clutch forward of the starboard halyard winch.  

Bow Sprit Control Line:  

The Bow Sprit Control Line leads from large padeye thru-bolted on forward 

bulkhead below deck, through the blocks on the bow sprit back through the bulkhead into anchor locker 
area, through the deck and aft through bullseye fairleads to rope clutch forward of starboard halyard 
winch.
