The luff tape is the weakest part of your headsails
Headsails fed into grooves, whether racing or cruising, will eventually experience an unavoidable chafe to the luff tape that connect the headsail with the forestay, ultimately resulting in breakdown and hence the sail won't hoist.

40 years of deterioration over
The Foilfeed® H1 puts an end to this problem once and for all by capping the end of the luff tape hence adding protection, strength and reliability to a fragile part of a sail. The unique and patented design represents 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 headsails 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'
Will be the connector part inside the groove, shaped in order to keep feeding as easy and quick as possible

3. Back- and forth feeding feature
Extrusions shorter than the actual luff tape luff will experience a feed back-into-groove-motion, when lowering the sail. The foilfeed® H1 takes care of that

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

5. Front slit
Dividing the Foilfeed® H1 so the luff tape can be placed inside for protection

6. Groove for stich protection
Stitches are lowered avoiding tear and wear compromising the fixture

7. Cover surface for luff tape
When foilfeed® H1 is being lowered onto the luff tape, the top edge will be covered, aligned and protected between the two surfaces

8. Groove for stitch protection
Stitches are lowered avoiding tear and wear compromising the fixture

1. Any tape solution. No Ease-out necessary
Foilfeed® H1 can be used on both single- and double roped tapes and is designed specifically for a 6 mm rope diameter. Tests have proven that diameters 5- and 7 mm works too on most setups, though it has to be determined by the individual setup. Just sew the tape onto the headsail without ease-out or any other protective arrangements.

2. Slide tape from bottom up into the Foilfeed® H1
Mount the Foilfeed® H1 gently onto the luff tape from the bottom. The luff tape shall slide in between the foilfeeds center slit. You may want to burn the top edge of the luff tape to help it slide better inside. Check out the 3D PDF above (Key Features) to see it in detail.

3. Slide Foilfeed® H1 firmly down
Press the Foilfeed® H1 firmly with it’s back onto to the sail side of the luff tape so that it is fully supported top to down on the inside. Align the outer rope and the ‘projectile with the 'spike’ pointing down the center of the rope.

4. Lower spike into rope
Slide the Foilfeed® H1 down firmly and position precisely, so the spike is completely lowered into the center of the rope. You may want to pre-poke with an awl or sailmakers needle all 25 mm down in the rope to make the lowering easier. The ‘Projectile’ and luff tape shall close the edges completely.

5. Stitch, finish and fly...
Stitch - with a sailmakers needle and waxed thread - both ends of the Foilfeed® H1 in order to lock the position firmly to the sail. Make sure your stitching is tight in order to stabilize the fixture. Your feeding will never be the same again...

Material

The Foilfeed® H1 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® H1 is designed to meet the geometrical requirements of all major suppliers of headsail furlings systems, foil extrusions and grooves, including feeders. Though the H1 is primarily made for 6 mm ropes, it has also proven usable on 5 mm and 7 mm ropes too, though it depends entirely on the actual setup.

The 'projectile' (item advanced into groove) is designed to be inserted both forth and back, meaning that a fully hoisted sail on too short an extrusion, will be able to feed back when lowering the sail again.

The spike (pin lowered into the rope) cannot break by either stepping on or by normal handling. It will only bend sideways. Since it is 25 mm long it will not be able to 'jump' out of position unless the whole area is being ripped apart.


Attaching Foilfeed® H1 to the sail is done by hand stitching. When tightening and securing the thread the sticthing will be lowered into the built-in grooves protecting it from tear and wear of general sail handling.

The Foilfeed® H1 weighs 19 grams.

Color and UV-resistance

The Foilfeed® H1 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® H1 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.
