How to measure your jib cover
L = luff length of the sail     G = Circumference at the clew (where necessary including sheet rope)
Please use measuring tape to measure your sail. Measure the length of your roller reefing foresail between the reel and halyard swivel. The jib cover needs to be able to be spanned tightly along its length.

    A Diekow jib cover reliably protects your sail from UV radiation, wind, and water. Decades of experience from sailing in practice and the use of the newest materials and insights shape the design of our sail covers.

    How do I protect my jib?
    Roller reef foresails remain fastened with most sailors during the season. As with the main sail, the foresail needs protection from UV radiation and environmental damages. There are a few options to substantially increase the lifespan of your sail:
    It is easiest to protect your sail with a jib cover after each cruise. This only takes a few minutes of your time, provided setting of the cover is quick and easy.

    The lower leech and foot edge is equipped with a broad strip of UV endurant fabric. If your sail supposed to stand when slightly furled (reefed) and produce more propulsion than tilt, the UV protectant strip is counter-productive. The thickened fabric at the lower leech and foot edge increases the circumference of the furled sail and pulls it flatter at the leeches, making it sag in the center. The thus developed bunt can barely produce any propulsion. Especially on charter yachts, sewn-on UV protection strips were a common method that has now been abandoned. Another option would be to completely produce the sail from UV-resistant materials which would still leave the problem of damages to the fabric from aggressive industrial emissions -- at least in our latitudes.

    The best, but barely practicable option: You retrieve the roller reefing sail after each cruise and store it below deck.

    We recommend our jib cover to you.

    Whats makes a good jib cover?
    A good jib cover should distinguish itself through reliable protection, easy handling and time-saving maintenance, and low prices in connection with a large size selection.
    protective function of the jib cover
    A smooth and tightly fitted jib cover offers little surface area for the wind to attack. Make sure the lacing rope can not detach in your absence. A loose sail cover that flutters in the wind not only bothers you and your neighbors at the landing but may also damage your sail, your rig and it may suffer damages itself.
    Stamoid is a super high-quality, coated textile made by Serge Ferrari in Switzerland. It is waterproof and silmutaneously possesses extremely high UV durability. These two characteristics protect your sail for a long time, while its rigidity ensures that once you have spanned your jib cover that tension remains. The smooth textile structure on the inside of Stamoid does not strain your sail with fibre chafing.
    A top-quality spiral zipper effortlessly absorbs the forces of the wind and the lacing. Its smooth inner surface preserves your sail.
    Attaching the jib cover D-Ring on Topp
    Ususally, a jib cover is attached to the snap shackle of the spinnaker halyard. A dee shackle is sown to the top of our jib cover. Thus, the metal of the snap shackle only ever touches the metal of the dee shackle, preventing wear, increasing stability, and allowing for a good load transmission onto the jib cover.
    Setting your jib cover
    Three steps are especially worth highlighting. Firstly, the pointed gable of the jib cover that easily slides across bumps. Secondly, a smooth-running zipper that zips shut with little effort; and lastly, a smooth inner fabric surface that slides across your roller reefing foresail without friction. Stamoid is a material with a very smooth inner surface, converving your foresail while setting and using it.
    Lacing of the jib cover
    The lacing of the jib cover combines a number of aspects. First and foremost, the circumference needs to fit. A circumference 10-20 mm larger than the largest circumference at the clew is appropriate. Too tight -- increases the effort while setting. Too wide -- increases the risk of your jib being too loose even when laced and for it to vibrate in the wind. From many years experience we have chosen circumferences that harmonize well with the lengths.
    We use our Diekow micro blocks for the deflection of the lacing cord. They ensure the cord is guided with as little friction and force as possible.
    The placement of the deflection pulleys, too, ought to be well thought out. If the deflection points are too close, their effect during lacing is minimal. If the points are too far apart, the unnecessary detour of the cords leads to higher friction. The consequence: increased expenditure of force and wear.
    We insert a so-called lacing border for cross-laced jib covers.
    lacing borderLacingThe lacing border works as an anchor for the micro blocks and distributes the force at the deflection points lengthwise, ensuring for the lacing to tighten the jib cover along the whole length of the luff.
    The smooth structure of stamoid also helps with lacing. On the inside of the jib cover because the material does not rub against the sail, and on the outside as the lacing cord does not rub against the jib cover.
    To conclude: Through an optimal combination of these aspects we can forego multilevel lacing cords. On the contrary. We deflect the lacing cord at the top in such a way that the cord has the same tension everywhere and tightens the jib cover consistently.
    Storage of your jib cover
    Light and thin material can easily be folded and needs little space in your locker. We recommend not to roll up but rather to fold the jib cover like an accordeon. The jib cover should not be stored too wet.
    Taking care of your jib coverThrough its Nanotop® anti-capillary treatment, stamoid is water and dirt repellent. Should it still take up dirt as time passes it can easily be cleaned with commercially available cleaning agents. You can keep the zipper smooth by occasionally rubbing it with stearin. Stearin is a compound found in candles. Just run a (white) christmas candle along the zipper. Also works with the zippers of your clothing.

    Tip: It is important for your jib cover to be able to be well tightened lengthwise. Upon special request we can also shorten your Diekow jib cover to your custom size (▸Sailmaker-service).
