Harken 40 mm Boot 369

Harken 40mm Boot – 369

The Harken 40mm Boot 369 is a durable PVC stand-up block boot designed to hold 40mm and 57mm Harken Carbo and Black Magic® blocks securely in place. It helps prevent snagging and keeps rigging systems tidy, improving line handling efficiency in high-performance sailing applications.

The Harken 40mm Boot 369 is a simple yet highly effective rigging accessory designed to improve the performance and organisation of sailing control systems. Made from durable, flexible PVC, the stand-up boot holds compatible blocks in an upright position, preventing unwanted movement and reducing the risk of lines snagging during operation.

By keeping blocks properly oriented, the 369 boot helps maintain clean lead angles and smoother line handling, particularly in fast-paced sailing environments where quick trimming and consistent performance are essential. Its flexible construction allows it to absorb movement and vibration while maintaining secure block positioning under load.

The boot is designed to fit both 40mm and 57mm Harken Carbo and Black Magic® blocks, making it a versatile addition to a wide range of dinghies, keelboats, and high-performance racing yachts. It is commonly used in mainsheet systems, control line setups, and other frequently adjusted rigging applications where block stability is important.

Lightweight and low-profile, the Harken 369 Boot integrates easily into existing systems without adding unnecessary bulk or complexity. At just 12.7g, it provides a practical performance upgrade with minimal weight impact.
