Arm a Windsurf Sail

Arm the sail
Refining the technique of assembling the sail is not a fussy or time-consuming thing … it’s just the opposite: arming early and well will allow you to get in the water first and have fun right away.


  1. In the first image we see what the final result will be;
  2. Mount the two halves together;
    unroll the sail with the wind at its shoulders gradually without waving the sail;
  3. put the tree in the sail until the top reaches the bottom of the tree pocket (if the sail has camber, leave it outside the hinges);
  4. insert the shaft extension and / or the downhaul, pass the sheet in the pulleys and set the minimum tension sufficient to stop the sheet in the cleat;
  5. take the boom and adjust its length up to the value indicated on the sail, approximating it by excess;
  6. at this point insert the boom and mount it as low as possible, being careful not to pinch the sail (note: in the end it will still be high but will not hinder the sliding of the sail during tensioning);
  7. pass the clew top in the sail and tension it without exaggerating: it will help you to slide the sail better during the downhaul tensioning, not to strain the splint pockets;
  8. pull the downhaul to the desired tension;
  9. In case of camber, tighten the clew, insert them and release the clew again;
  10. loosens the clew tension to the desired point; Bring the boom to a height between the shoulders and the chin.
  11. Splints: the current sails have fixed ribs (first image). If you have a sail that still has slat adjustment, tension starting from the highest one (see second image).
  12. To facilitate the tensioning of the downhaul on large sails, we strongly recommend the use of a winch (see third image). The compression that is generated on the back in this operation is considerable
