Club FJ Rigging Guide
Click on a topic, or simply scroll the page to read through the guide


Congratulations on your purchase of Vanguard Club Flying Junior sails produced by North Sails. We are confident you will find superior speed over all conditions and long-lasting durability. Your new Club Flying Junior sails are designed to be fast and easy to trim.  
The following measurements are those we have found to be the fastest for your new North sails. We urge you to set your boat to these specifications when tuning your boat. This will help you achieve consistency in boat speed, and will serve as a basis for future tuning. If you have any questions or problems or are not able to get your boat to match up to these specs, please feel free to call us here at the loft.

ONSHORE ADJUSTMENTS

 
STEP 1:
Before stepping the mast, check the length of the free-swinging spreaders on the mast. These spreaders are measured from where the wire runs through the tip to where the spreader is butted up against the side of the mast. This measurement should be 15 1/2" to 16".
 
STEP 2:
When stepping the mast, check the measurement from the centerboard pin to the back of the mast. This measurement should be 16 1/4" to 17".
 
STEP 3:
Attach the forestay to the stem plate at the bow in the 2nd hole back.
 
STEP 4:
Hoist a tape measure on the jib halyard to the top of the mast. Measure down to the forestay attachment point at the bow. This measurement should be approximately 13' 2".
 
STEP 5:
Attach the shrouds in their respective chainplates so the rig is just snug.
 
STEP 6:
Hoist the tape measure on the main halyard all the way to the top and measure back to the top of the transom at the back of the boat. This measurement should be approximately 20' 10" to 21' 0".
 
STEP 7:
With your tape measure still attached to the main halyard at the top of the mast, check the placement of the mast sideways in the boat. Take a measurement to one side directly across from the shroud to the underside of the rail. Next, take the tape to other side and check the difference of the two measurements. It is unacceptable if the difference is more than 3/4".
 
MAINSHEET TRIM AND BOOMVANG:
The mainsheet should be pulled tight enough so the upper batten becomes parallel to the boom on a vertical plane. This is sighted from underneath the boom looking up the sail and lining the batten and boom on that plane. In light winds it is impossible to keep the upper batten from hooking slightly to windward because of the weight of the boom hanging on the leech of the sail. In choppy conditions or after a tack, ease your mainsheet approximately 6" to open the upper batten slightly past parallel to the boom. This allows the mast to straighten slightly and the main to become fuller. When the boat becomes overpowered the boomvang is used to help hold the boom down and keep the upper batten parallel to the boom. The mainsheet will then act as a traveler. When a puff hits, with the boomvang on hard, the mainsheet will simply be eased off so the boom will move to leeward and depower the boat. The heavier the winds, the heavier the boomvang tension. Always aim at keeping the upper batten parallel to the boom. Unless sailing on open water or longer courses we have found it is never necessary to use the traveler. 95% of the time the traveler is left cleated in the center of the boat.
 
Downwind, the vang should be trimmed enough to keep the boom down and the leech set with the upper batten parallel to the boom. There is a telltale placed on the upper batten on your North mainsail which should flow straight off the leech when the boomvang is set properly downwind.
We wish you good luck and fast sailing!
