The luff tape is the weakest part of your mainsail
Mainsails fed into grooves - typically racing yachts (From 60 footers, One Design classes to small dinghys) - will eventually experience an unavoidable chafe to the luff tape that connect the mainsail with the mast, ultimately resulting in breakdown and hence the sail won't hoist.

40 years of deterioration over
The Foilfeed® M1 puts an end to this problem once and for all, by both capping the end of the luff tape, shielding the mast from a chafing headboard and hence adding protection, strength and reliability to a fragile part of the mainsail. The unique and patented design represent a solution to what has been a continous weakness of sails being hoisted in grooves for almost four decades. Now, that problem is over...

Foilfeed® on your sail is a sign of quality
Displaying a Foilfeed® on your sail sends a message, that you apply state-of-the-art protection to your luff tape solutions, emphasizing quality, design and durability. It's smart, less cumbersome to keep the mainsails in perfect order and there's no way you will be going back to old solutions once you've had a foilfeed on your luff tapes.

1. The feeding 'Fin'
This part is the part replaces the weakest part of the luff tape - the edge. Thanks to the durability of the material, this part can be fed on and on and on...

2. The 'Projectile'
The connector part inside the groove, shaped in order to keep insertion and feeding as easy and quick as possible. Even with cold fingers!

3. Cutouts to lighten Foilfeed® M1
Weight reduction is a key feature, since the Foilfeed® M1 solution is by far the lightest solution in the industry. And nobody wants to put weight aloft unless absolutely necessary. A gram aloft can mean a kilo on deck... The Foilfeed® M1-10 weighs 23 gram; A typical industry solution around 70 gram!

4. Groove for stitch and rope fixture
Stitches are lowered into a groove avoiding tear and wear compromising the fixture. The stitching into the rope stabilizes both the Foilfeed® M1 and fixes the rope to keep the desired tension

5. The Spike
This part is to be lowered into the rope in order to align perfectly

6. Front slit
Dividing the Foilfeed® M1 so the luff tape can be placed inside for protection

7. Headboard cover rail
Build-in rails that protects the mast from being chafed by the headboards edges when bend out. Since the Foilfeed® M1 is made of Delrin® it will keep friction at a minimum

8. Fixture surfaces inside headboard plates
The surfaces are mounted on the outside of the reinforcement, fixing the Foilfeed® M1. Headboards will be mounted on the outside. The two surfaces phase out in thickness to 0,2 mm on the edges, making the load transition from reinforcement, through the Foilfeed® M1 to the headboard perfectly smooth

1. Determine the final headboard position
Mark the top of your mainsail where you will mount the headboard. This top will also be the top of Foilfeed® M1.



2. Make cutout. Same dimensions whether 8, 10 or 12 mm
Measure - from the back of the rope (sail side of rope) - 10 mm in and 100 mm down. Cut this area out. You may want to burn both the edges and the rope.

3. Slide Foilfeed® M1 firmly down from top
Press the Foilfeed® M1 firmly with it’s back onto to the sail side, so that it is fully supported top to down on the inside of Foilfeed® M1's back. Align the outer rope and the ‘projectile with the 'spike’ pointing down the center of the rope. You may want to pre-poke the crusted surface of the rope with an awl in case you have burnt it. The ‘Projectile’ and luff tape shall close the edges completely.

4. Lower spike into rope and hand stitch
Stitch - with a sailmakers needle and waxed thread - in order to fix the rope position firmly to the sail. Make sure your stitching is tight in order to both stabilize the fixture and to make it solid for pulling the cunningham and maintaining the desired rope tension.

5. Place headboard correctly and mark up holes
Press the Foilfeed® M1 back to back with the cutout and place the headboard plate correctly and start marking up for the final hole punching. Line up the top of both Foilfeed® M1 and the headboard vertically. Push the headboard all the way to the built-in mast cover rails (no chafe between headboard and surface of mast).

6. Punch holes and assemble headboard
Punch all the holes needed, fix headboard on both sides with rivets or bolts (whatever standard) and press the liner for the halyard. With a foilfeed® M1 your feeding will never be the same...

Material

The Foilfeed® M1 is made of Delrin® POM due to its strength, durability and its non-friction properties. The homopolymer grades (Technical name for Delrin®) have a higher mechanical strength, stiffness, hardness and creep resistance as well as a lower thermal expansion rate and often it also presents a better wear resistance. Delrin® is designed for applications requiring low wear and/or low friction against steel, itself and other plastics.

Delrin® POM is used in many static and dynamic industrial applications replacing materials like steel brass, bronze, copper & aluminum. Polyacetal have improved part life because of better wear, more chemical, corrosion and UV-resistance. These materials reduce noise and will reduce or eliminate the need for lubricants. Delrin® POM can be used in applications such as Gears, Bushings, Bearings, Rollers, Timing Screws, Manifolds, Valves & Valve bodies, Washers, Wear pads and many industrial machine parts.

Main Characteristics of Delrin® POM: • High mechanical strength, stiffness, hardness and toughness • Excellent resilience • Good creep resistance • High impact strength, even at low temperatures • Very good dimensional stability • Good sliding properties and wear resistance • UV-resistant

Geometry and design

The Foilfeed® M1 is designed to solve the old problem with chafing luff tape, improving functionality and at the same time building in some features not found in the existing solutions, saving the sailmakers 3-5 handwork routines at the same time.

The 3 variants - made for rope thicknesses 8 mm, 10 mm and 12 mm - is also expandable at the surfaces underneath the headboard plates, enabling various dimensions of reinforcements to fit inside as desired.

Whatever M1 variant you may choose, the cutout dimension is the same (10 by 100 mm), so that sailmakers easily can remember dimensions.

The 10 mm version weighs just about 10 grams making it the lightest solution possible.

The height of the mastcovers keeps headboards of 3 mm thicknes clear of masts and due to the material Delrin® POM, friction is kept at the lowest level.

Color and UV-resistance

The Foilfeed® M1 is made of bright white Delrin POM. There are two main reasons for that:

1. Aethstaetics: Since all standard fittings, tapes and other nylon additions to a sail is white, the Foilfeed® M1 will fit in the general looks and design from all major sailmakers worldwide.

2. UV-resistance: The color white is best to reflect the UV from the sun and furthermore, the Delrin® POM has been mixed with 2% UV-block in the moulding process making it more resistant to UV radiation, hence less degradable than most plastic products over time.
