Code zero furler5/7/2023 Simple attachment systems allow either a conventional snap shackle or a 2:1 block either on top of the swivel or below the spool.ĭrum Diameter 3 5/32", Lower Unit Height 3 7/8", Swivel/Shackle Dia. CODE ZERO (STANDARD FURLING) typical maximum boat size SERIES Monohull LOA Multihull LOA Sail Area M.W.L. All KF Furlers are maintenance free and protected by a special anodizing with Teflon impregnation. For boats 33 feet and smaller, sails are small enough that a furler is not necessary. The torsional load is shared by the cable and sail luff to furl the sail. bottom-Up Sets Bottom-up (BU) furlers are the most common choice for code zero and staysail furling. Furler sets typically consist of drum and top swivel, plus any attachments / accessories. This is also convenient for quickly clearing the foredeck. High resistance stainless steel ball bearings ensure smooth rotation under the most extreme loads. There are three different methods for controlling a cruising Code Zero. An extensive range of furling systems for code zero, gennaker and staysail. A FURLER FOR FLYING SAILS : - Large Gennakers, Code Zeros, and Staysails are easy to handle using Facnor furlers. Inc reased available luff length through reduced height of the spool and tack fitting, putting the tack of the sail closer to the deck. Effective on any point of sail between 45 and 180 off the wind, it’s a no-nonsense, light-air solution that is capable of moving us along at about one half of the apparent wind speed, or better, when the breeze is less than eight knots apparent. The Code Zero is a cross between a genoa and an asymmetrical spinnaker that is used for sailing close to the wind in light air. Continuous line systems allow unlimited furling (ideal for large overlapping sails), and larger diameter drums apply more torque for easier operation. Our most basic light-air strategy is to fly our code-zero type drifter. Simple line replacement: KF Furlers have a notch on the spool allowing fitting or removal of the loop line without removing the line cover or dismounting the system. Protective Spool Cover: An elastic impact-resistant plastic cover encloses the lower spool. ![]() Karver furlers dominate in extreme offshore racing classes like the Open 60, and here are a few reasons why: In addition, a single furler may be utilized on numerous sails (gennaker, staysail, stormsail, etc.) improving sail handling. Drums incorporate a machined groove profile and cross-hole geometry to grip the furling line securely. Advanced drum technology The range matches drum diameters to load ratings providing the optimum balance between speed and ease of furling. Raise the rolled sail, and simply unroll it and set the sheets. Furlers to suit boats from 5m (16') to 25m (82') Features 1. The rolled sail is easily removed from the sail locker, the drum attached to the deck and a halyard attached to the swivel. ![]() ![]() Unlike conventional reefing systems that are fixed to the headstay 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 and storing the rolled sail, minimizing weight and windage aloft.
