Run the tape the shortest route along the aft deck to one side of the console down to the step. 20mm aft of standard in light airs and 10mm forward of standard in fresh conditions. Note you will have to make an allowance on Mast Chocking by about what you move the step. The wire passing through each spreader tip to be located 25mm aft measured from a straight line square across the front edge of the mast. Check mast is square in boat by measuring from chain plate to chain plate with the jib halyard or tape measure from hounds.
Lowers are to be fine tuned on the water.
Rake Disconnect forestay above deck and swing it into the mast and mark the top of the gooseneck black bands onto the forestay. Reconnect the forestay and set the rake up at a distance of 1.17m measured from the black band mark down to the deck following the forestay. Sheet the jib on firm and the clew should be just becoming block to block when the jib car is set up for sailing in medium air. If the clew is too high lengthen the forestay, if low shorten forestay. If you adjust your mast step the chocking will have to be revised accordingly.
