    Product Description


    The rollers sit in the newly developed cup so that they are protected from damage while preventing injuries. This arrangement ensures an absolutely frictionless alignment of the downhaul rope in combination with 0° tack rollers (e.g., North Sails, NeilPryde, Gaastra, ...) as well as with 90° rotated roller units (e.g., Gun Sails, Naish, Severne). This saves power by reducing the friction and protects the rope. At the same time this arrangement for the first time allows the loop-loop-go function with absolutely all sail brands! Means no annoying and time-consuming threading through the rollers - simply loop the rope-loop over the two outer tack rollers and you can immediately start downhauling.

     Through the intelligent positioning of the cleat, for the first time it is now possible to prop with both feet against the cup, and thus cope far greater forces avoiding lower back strain. Now you can use the same technique for the downhauling as in rowing, where you naturally also use both feet to mobilize maximum power through pushing with the feet rather than pulling through your back. That increases the power efficiency by approx. 30% compared to the usual one foot operation! 

    Due to the modified position of the standard cleat, just place one foot on the extension and pull the rope with a short jerk out of the standard cleat - done.



    • Quick loop and go pulley access.
    • Frictionless threading of downhaul rope no matter which way the sail pulley is orientated.
    • 2 foot downhaul ability equating to 30% more downhaul power.
    • Easy one foot downhaul rope release.
