The KTS 4.5 is an adapter that allows you to stow an asymmetrical spinnaker.
This adapter installs directly into the fork of a furler of the same capacity (KTS 4.5 for KF 4.5). The sail's tack is attached to the KTS swivel, so only the top of the sail furls during the first turns of the furler. The sail is thus smothered from the top and gradually furls its entire length around the anti-twist line that connects the furler turret and the swivel.
A simple and effective system that makes it very easy to maneuver a spinnaker from the cockpit. The KTS is clearly an alternative to the spinnaker sock.
Fits on KF 4.5
Requires an anti-twist textile cable between the drum and the swivel
