Track position (fore and aft) - Measure from the forestay attachment point at the deck, to the front of the Genoa track.ĩ. Feeder heigh - Measure from the bearing surface of the shackle on the furling drum to the bottom of the feeder.Ĩ. This ensures that there will not be any hard spots up the luff of the sail.ħ. ![]() Tack set-back - Measure the tack set-back from the aft side of the foil to the bearing surface of the tack swivel. What color sunshield do you want? Which side of the sail do you want it on? * pass the tape around the outside of the shrouds as the leech of the sail would.Ħ. Measure from the centerline of the boat to the track. Measure from the swivel shackle (or halyard for hank-on) to the front of the Genoa track. Measure from the forestay attachment point at the deck to the front of the Genoa track. What is your preferred clew height (low at lifeline height, or higher near boom height?). What kind of furling unit do you have, or do you have hanks?_ Measure from the headsail tack attachment point to the bottom of the feeder_ Measure from the back side of the foil to the bearing surface of the tack shackle_ Measure from the bearing surface of the halyard attachment to the bearing surface of the sail attachment. Measure from the bearing surface of the shackle to the center of the forestay pin measure from the center of the forestay pin to the deck_ © MAX LUFF (for furling) measure from the bearing surface of the swivel shackle, to the bearing surface of the drum shackle_ © MAX LUFF (no furling) measure from the halyard attachment to the bearing surface of the tack attachment (for hanks)_ Measure from the forestay attachment point at the deck to the front of the mast Measure from the intersection of the forestay and the mast down to the deck_ IF NECESSARY MEASURE A FEW TIMES AND SEND US THE AVERAGE. STRETCH YOUR TAPE MEASURE AS TIGHT AS YOU CAN AND TAKE THE MEASUREMENT. Measure from the bearing surface of the halyard attachment to the bearing surface of the sail attachment. Furling Swivel - Note that if you have provided the max luff length and drum height, this dimension will not be absolutely necessary, but it's always important to give your sailmaker as much information as possible. Height of Forestay Pin - Include the height of the forestay pin by measuring from the center of the forestay pin to the deck.ĥ. Measure in stages: first to the top of the drum, then the height of the drum, and finally to the forestay pin.Ĥ. ![]() Measure from the bearing surface of the tack shackle to the center of the forestay pin. Drum height - This measurement lets the sailmaker know how high the furling drum is off the deck so that he can calculate where the sail will sheet to be sure that it hits the track on the deck. If there is going to be a furling unit on the stay, attach the tape measure to the masthead swivel, hoist it as high up the forestay as it can go, and measure to the bearing surface of the shackle on the furling drum.ģ. This dimension is for a sail that is going to be attached with hanks. Max luff length - With the tape still at the top of the mast at a full-hoist position, measure to the bearing surface of the tack attachment of the sail. The lower point of I is relative to the height of your freeboard and some other factors, but for a sailmaker's purpose this is sufficient.Ģ. Now measure to the base of the mast for your I dimension. Be sure to attach a retrieval line so that you do not have to rely on the tape for pulling the halyard back down again. Height of I - If you do not have a sailplan and would like to know your I dimension, attach a tape measure to your Genoa halyard and hoist the halyard to the top of the mast.
