Karver KFV3 KTS adaptor is designed to be fitted onto the KF furling range to convert the bottom-down furler into a top-down furler for use with an asymmetric spinnaker. The KTS adaptor is available in sizes 1.5, 3.0 and 4.5-6.0, and can be used across all 4 ranges; standard, racing, classic and structural.

The KF V3 range is the third furling range from Karver, to be used with the flying sails of the gennaker, code-zero or staysail.
