    What to do if my Selden Furlex 100 S sail will not unfurl?
    • K
      Keith HernandezAug 20, 2025
      If your Selden Marine Equipment sail won't unfurl, or only partly unfurls, it could be due to several reasons: * The jib halyard or another halyard might be wrapped around the luff extrusion. Ease the halyard slightly and try to reverse the system. * The furling line may not be free to run or has become tangled. Furl the system and free the halyard. * The forestay might be too slack. Tension the forestay, first by tensioning the backstay adjuster or backstays. If that doesn’t help, decrease the length of the Furlex system. Adjusting the forestay. * Dirt and salt in the bearings can cause this issue. Rinse the bearings with fresh water and lubricate with Furlex grease. * Too much strain on the halyard can also prevent unfurling. Ease the halyard off.

    What to do if my Selden Furlex 100 S Marine Equipment sail unfurls after reefing?
    • C
      Christian LewisAug 23, 2025
      If your Selden Marine Equipment sail unfurls after reefing or furling, it could be because: * The sail isn't furled tightly enough. Furl with some drag on the line. * The furling line isn't belayed. Furl and belay the furling line.

    Why does my Selden Marine Equipment system wobble when furling?
    • M
      Matthew BellAug 26, 2025
      If your Selden Marine Equipment system wobbles when furling and unfurling, the forestay might be too loose. To fix this, tension the forestay and/or backstay.

    Why is my Selden Furlex 100 S Marine Equipment sail hard to hoist?
    • C
      cameron83Aug 28, 2025
      Your Selden Marine Equipment sail might be hard to hoist due to these reasons: * The luff tape might be too thick. Return the sail to the sailmaker. * The sail might be caught on something or is not sufficiently loose on the foredeck. Arrange the sail better on the foredeck. * There could be a fault in the halyard routing. Check the sheaves, winch, etc. * Dirt and salt in the luff groove can cause friction. Clean the luff groove.

    What causes wrinkles at the tack of my Selden Furlex 100 S sail?
    • D
      Denise RobinsonAug 31, 2025
      Wrinkles at the tack of your Selden Marine Equipment sail can occur because: * The tack ring was twisted in the wrong direction before tacking the sail. Unfurl the sail, ease off the halyard, undo the tack snap shackle, rotate the tack ring around the system, and retack the sail. * The sail is old or incorrectly cut.

    Why can't I tension the luff on my Selden Furlex 100 S Marine Equipment?
    • P
      Peter SharpSep 3, 2025
      You might not be able to tension the luff of your Selden Marine Equipment because: * The halyard swivel comes into contact with the top guard. The luff of the sail is too long. Have the sail shortened by the sailmaker. * The angle between the forestay and the halyard is too great. Shorten the sail or move the halyard lead up.

    What to do if I cannot take down my Selden Furlex 100 S Marine Equipment sail?
    • E
      Eric FarleySep 5, 2025
      If you cannot take down your Selden Marine Equipment sail: * The halyard might be wrapped around the top of the luff extrusion. Ease the halyard off and try to reverse the system. * The halyard wraps around the luff extrusion as the sail is coming down. Tension the halyard manually, keeping a slight drag on it while taking the sail down. * The halyard is stuck. Check the halyard routing (sheaves, stoppers, etc.).

    Why is the UV protection on the inside of my Selden Furlex 100 S furled sail?
    • J
      Jessica PattersonSep 8, 2025
      The sail’s UV protection might be on the inside of the furled sail because the furling line is wound on the drum in the wrong direction. Remove the sheet from the sail and gather the sail around the Furlex system with a rope. Pull on the line until the drum is empty. Wind a couple of turns on the drum by hand in the right direction. Unfurl the sail. Furl again, checking the number of turns of furling line on the drum.

    Why does the leach flog on my Selden Furlex 100 S sail?
    • T
      thompsonnicholeSep 12, 2025
      The leach of your Selden Marine Equipment sail might flog despite sheeting hard due to: * An incorrect sheeting point. Move the sheeting point forward. * An incorrectly tensioned leach line. Adjust the leach line.

    Why does the leach close on my Selden Marine Equipment sail?
    • T
      Theresa BergSep 13, 2025
      The leach of your Selden Marine Equipment sail might close (bend inwards) due to: * An incorrect sheeting point. Move the sheeting point backwards.
