Karver KSW52 Speed Winch - 4-Speed Winch - Stainless

The Karver KSW52 4-speed winch with stainless steel drum delivers exceptional performance for larger yachts, combined with a premium, traditional finish. Featuring a polished 316L stainless steel drum, this version offers all the speed and efficiency of the KSW range with enhanced durability and a classic look on deck.

At the core of the design is Karver’s advanced 4-speed automatic system, providing two standard speeds alongside two ultra-fast gears. Gear changes are achieved simply by reversing the direction of rotation, with the winch automatically returning to first gear when the load is released for smooth and intuitive operation.

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 while helping maintain boat speed and reduce crew effort. The self-tailing system eliminates the need to manually take up slack, ensuring manoeuvres remain smooth, safe and controlled.

Key Features:

• 4-speed automatic winch with ultra-fast gear system
• Polished 316L stainless steel drum for durability and corrosion resistance
• 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 rope handling
• Designed for larger yachts and high-load applications

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

The 316L stainless steel drum provides excellent resistance to corrosion and wear, making it ideal for long-term use in harsh marine environments. Combined with Karver’s precision engineering, this winch delivers both performance and long-term reliability.
