KSF Top Down Spinnaker Furlers

Karver products are renowned across the racing and cruising world for quality of design and performance in the most demanding environments. The Karver furling systems are the 'premier' league with the extensive choice, quality and comprehensive spare options. 

Why choose a flying furler?

• The furler is a light and removable system that quickly launches the foresails on your sailboat. Free flying sails come as an addition to your genoa so you always fly the best sail depending on the wind and boat direction.
• A furled sail is easier to handle and can be readily stored below out of the way.
• The same furler can usually be used for several types of sails: gennakers, stormsails, staysails and more recently on asymetrical spinnakers.
• The choice to design the Karver furler with a composite spool around the drum was made to protect fingers from getting caught when operating the unit and prevent the furling line from jamming out. As well, it was also designed to enable the furling line to eject when not under tension.

How Does It Work - Straight Luff vs Top Down Spinnaker?:

Free Flying Sail - Straight Luff Furler e.g. Karver KF - 

• Anti-torsion cable is sewn inside the sail luff.
• The tack and the head of the sail are attached with a lashing to the anti-torsion cable (thimbles).
• The sail starts furling from the bottom (like a jib furler).

Top Down Furler e.g. KSF Furler System or KTS Top Down Adaptor - 

• KF standard furler, featuring a tack swivel on top of the drum.
• The tack of the spinnaker is attached to the tack swivel. The head of the sail is attached to the anti-torsion cable (thimbles).
• The anti-torsion cable is separated from the sail luff which transfers the torque from the drum to the top swivel. This is the essential part of a good furling process.
• The sail starts furling from the top downward.
