Karver products on sale

A furler is the ideal system to set and strike light sails. In a race utilising multiple furlers for various sails, Karver offers the advantage of roller furling without the weight & windage of a conventional roller reefing system. K.F. furlers optimize sail handling with minimal weight aloft.
Karver is an industy leader in this concept offering a complete range of superior products for all sailors.


Unlike conventional reefing systems that are fixed to the stay and have rigid extrusions, a furler is a light cast off system that allows ease of deploying and striking a sail with the added convenience of lowering the rolled sail for ease of stowage, minimizing weight & windage aloft.
The rolled sail is easily removed from the sail locker, the drum attached to the deck and a halyard attached to the swivel. Hoist the rolled sail and simply unroll it and set the sheets. In addition a single furler may be utilized on numerous sails (gennaker, staysail, stormsail…), improving sail handling and overall safety aboard.


  • FURLING DRUM: Karver’s furlers have a notched self locking wheel to make the continious line smoothly grip the wheel. The mechanism is made of V-shaped, angle less grooves to avoid the wear on the rope while assuring an optimum movement even when the rope is not under load. This wheel is protected in an elastic plastic spool. This system is safer than any other: after a shock the spool takes it’s shape back and will not restrict the wheel rotation. This feature is exclusive to plastic spooled furlers, a metallic spool would simply distort, deform the furler and dramatically reduce rotation, possibly even jamming.
  • UPPER SWIVEL: The loads applied to a furler are particularly high on the swivel. Karver utilizes high resistance stainless steel ball bearings to ensure smooth rotation under the most extreme loads.


K.F. furlers have a notch on the spool allowing fitting or removal of the loop line without removing the line cover or removing the furler from the yacht., this has the following advantages

  • Eliminates the need to remove the cover & avoids the risk of loosing small parts (screws, pins…),
  • Keeps the mechanism closer to the deck by avoiding the necessary displacement required for removeable covers,
  • The loop line is simply & quickly engaged or removed from the spool through the notch.
  • Increases available luff length by minimizing the height of the spool & tack fitting

Also available are the Karver top down furlers enabling the furling of a full A-symmetric spinnaker. See video by clicking here
