The Karver KSW46 4-speed winch is a high-performance sailing winch designed for fast, efficient sail handling on larger yachts. Featuring an advanced 4-speed automatic system, it combines the power of a traditional 2-speed winch with two additional ultra-fast gears, delivering exceptional speed and control under load.
Gear changes are achieved simply by reversing the direction of rotation, just like a standard winch. The system automatically returns to first gear when the load is released, ensuring smooth, intuitive operation during manoeuvres.
The KSW46 retrieves line up to 6 times faster than a comparable winch, dramatically reducing the number of handle turns required. This results in quicker tacks, gybes and hoists, while maintaining better boat speed and reducing strain on both crew and sails. The self-tailing design also removes the need to manually take up slack, making it ideal for short-handed sailing and racing applications.
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
- Ideal for racing yachts and short-handed crews
The Karver KSW range is widely used on performance yachts, including Class 40 race boats, where fast and efficient line handling provides a clear advantage. Improved control reduces sail wear, maintains sail shape and helps retain speed through manoeuvres.
Manufactured from hard anodised aluminium, the KSW46 is built for durability in demanding marine environments. Corrosion-resistant materials and a robust design ensure long-term reliability with minimal maintenance.
