KRS Reefing Furlers: A Model for Each Boat

Karver KRS reefing furler selection chart: KRS20 to KRS50 by boat length in metres and feet, maximum forestay diameter and genoa area

Three parameters define the choice: forestay diameter, boat length and sail area. Forestay max. reads "without / with removable end fitting" (mm).

* Including short lower extrusion. ** The value delivered as standard is printed in bold in the catalogue; change at no extra cost on request. All models: elliptical double groove foil, removable drum and luff line guide; long and intermediate plates, turnbuckle cover and closed carbon drum are options.

  • Add or remove 2 m profiles to suit your forestay length (each kit includes between 5 and 10 profiles; adjustment on request).
  • Forestay with a turnbuckle: you need the turnbuckle cover option, unless the turnbuckle sits under the drum with long link plates.
  • To raise the drum (anchor passage, chainplate), replace the standard short plates with longer ones (M, XL).
  • Check that the standard lower pin fits your deck plate or chainplate; ask for another diameter if needed.
  • Replacing the furler but keeping the sail: check the groove is compatible (5 mm in most models).

Power ratios and tailing lengths for each speed are on catalogue pages 70–72.
