Karver KSW52 Speed Winch - 4-Speed Winch

The Karver KSW52 4-speed winch is a powerful, high-performance sailing winch designed for larger yachts and demanding sailing conditions. Featuring an advanced 4-speed automatic system, it delivers the capability of a traditional 2-speed winch with two additional ultra-fast gears for unmatched speed and efficiency.

Gear changes are controlled simply by reversing the direction of rotation, just like a standard winch. The system automatically returns to first gear when the load is released, providing smooth, intuitive operation during manoeuvres.

The KSW52 retrieves line up to 6 times faster than a comparable winch, significantly reducing the number of handle turns required. This allows for faster tacks, gybes and sail hoists, helping maintain boat speed while reducing physical effort. The self-tailing design eliminates the need to manually take up slack, making it ideal for racing yachts and short-handed crews.

Key Features:

• Innovative 4-speed automatic winch system
• Two standard speeds plus two ultra-fast additional speeds
• Up to 6x faster line retrieval than equivalent winches
• Automatic gear changes via rotation direction
• Returns to first gear when load is released
• Self-tailing design for secure and efficient rope handling
• Reduces effort and improves manoeuvre efficiency
• Designed for larger yachts and high-load applications

The Karver KSW range is widely used on performance yachts, including Class 40 race boats, where fast and efficient line handling provides a competitive advantage. Improved control reduces sail wear, maintains sail shape and helps retain speed through manoeuvres.

Constructed from hard anodised aluminium, the KSW52 is built to withstand harsh marine environments. Corrosion-resistant materials and a robust design ensure long-term reliability while remaining easy to maintain.
