Karver K SNAP KF3.0: Dual-Purpose Snap Shackle Retrofit for KF3.0 V3 Furlers

The Karver K SNAP KF3.0 is a retrofit accessory designed to enhance the functionality of your Karver KF3.0 V3 furler, replacing either the standard 3:1 friction sheave or lashing eye with a single, versatile fitting. This is the same K Snap installed on the KF3.0 Standard Version, now available as a standalone upgrade for existing systems.

Two Modes – One Compact Solution

The K Snap offers dual functionality in one integrated unit:

• Standard Snap Shackle Mode – Enables quick, secure attachment to a fixed chainplate or pad eye.
• 2:1 Purchase Mode – Route your tack line through the built-in sheave for a 2:1 mechanical advantage, allowing easier sail tensioning and more precise control.

This makes the K Snap ideal for sailors who want the flexibility to adapt their furling setup based on wind conditions or performance goals.

Installation Guidance

Retrofitting the K Snap KF3.0 requires partial disassembly of the furler drum to remove the original lashing point or friction sheave. It is not a tool-free swap, but the process is straightforward, and Karver provides a detailed video walkthrough:
