RESTORE SAIL PERFORMANCE WITH A PRECISION RECUT SAIL PERFORMANCE IS SHAPE DEPENDENT Sail shape and minimizing stretch are two key variables in delivering optimum upwind performance and reducing heel and weather helm. These factors also extend a sail’s wind range before a sail change becomes necessary. Quantum’s Precision Recuts give new life to racing sails by restoring the sail up to about 90% of its original shape. Reshaping techniques can be applied to both Dacron® and membrane sails to yield a sail that will allow you to point higher, sail faster, and is easier to trim. The condition of the sailcloth is key; it must not be too worn and stretchy or the adjustments will not produce the desired results. With good fabric, reshaping can generally be done once or twice during the life of a sail. Working behind the scenes for top-level race programs are sailmakers who continuously tweak and recut sails to maximize boat speed and sail performance while working within sail limitations. With Quantum’s Precision Recuts, club and weekend racers can enjoy the same performance benefits and competitive advantage of top teams like Quantum Racing. Following are three of the most common ways to recut a sail to restore optimal performa

BROAD SEAM RESHAPE New seamline is rejoined at the location of the original seam BROAD SEAM Existing broad seam Cut and remove extra fabric BROAD SEAM DETAIL Reshaping 3-5 broad seams will help flatten the entire sail. PROBLEM: DEEP DRAFT. FULL SAIL. CAN’T POINT VERY HIGH. The sail depth becomes fuller and more rounded. The draft moves aft. You’re no longer able to point as high as when the sail was new. An inability to hold a lane or position close to other boats can really destroy a tactical game plan. SOLUTION: SEAM RESHAPE Seams are reshaped and extra fabric is removed. This procedure flattens...

LUFF CURVE RESHAPE RED: REDUCE LUFF CURVE GREEN: ADD LUFF CURVE Luff curve can be removed or added to help return sail to original entry shape. PROBLEM: REDUCED ENTRY. SAIL IS HARD TO STEER. As sails age, their entry is reduced due to a variety of factors. Stretch, as well as over-tensioning the halyard can reduce entry. Reduced entry will make the sail harder to trim, less efficient and make steering more difficult. SOLUTION: LUFF CURVE CHANGE Luff curve can be restored to help return the sail to its original entry shape. Sometimes a luff curve change is made to remove entry and flatten the sail. RESULT:...

LEECH TAKE-UP CUT AND REMOVE EXTRA FABRIC The leech length can be shortened and straightened by removing extra fabric along a seam or elsewhere. PROBLEM: LEECH FALLS AWAY. SAIL ISN’T DELIVERING POWER. On cruising Dacron® mainsails and genoas, the leech can stretch and fall away, making the sail more difficult to trim and reducing boat speed. Leech stretch can also hamper the use of furling systems. SOLUTION: LEECH TAKE-UP By removing extra fabric at a seam or elsewhere on the sail, the leech can be shortened and straightened to its original dimensions and shape. RESULT: SMOOTH LEECH WITH PROPER...

NEW SAIL PERFORMANCE AT A FRACTION OF THE COST Older sails in good condition can be reshaped to return the sail to peak performance at a cost far less than the price of a new sail. Generally speaking, a recut will cost less than 20% of the price of a new sail. Speak with your local Quantum sail consultant for more detailed pricing. HOW DO I KNOW IF MY SAIL IS A GOOD CANDIDATE FOR RESHAPING? If you are experiencing any of the problems noted above, contact Quantum Sails and we will happily perform a sail shape analysis and provide you with the results and an estimate at no charge. The analysis requires...

TIPS FOR TAKING PHOTOS OF YOUR SAIL FOR RECUT ASSESSMENT 1 Sail must be full, on a close hauled course, trimmed correctly. 2 Photos should be taken from the mid-foot of the sail in question, with the lens aimed at the head of the sail. 3 Rotate the camera to capture the full length of the lowest draft stripe. 4 Take a variety of photos from this location, as well as photos of any specific problem area on the sail. 5 Where practical, take a few photos from the stern of the yacht, with the lens pointed forward toward the bow, and up towards the head of each sail. 6 It is very important to note the...
