Introduction

The 57mm diameter Carbo Ratchamatic® block is an innovative solution for sailors who value both performance and ease of use. This load-controlled ratchet block gives you the ability to sail with low resistance while maintaining control of your sheets when the demands increase.

Functionality

Load-controlled design:
When the load is low, the block runs freely in both directions, while the ratchet is automatically activated when the load increases.
Seamless switching:
The transition between ratchet and light wind operation is smooth, so that unloaded sheets run out at lightning speed.
Optimum holding force:
The holding force of the 57 mm disc is up to 10:1, which ensures optimum control in various sailing conditions.

Adaptability

Easy adjustment:
With a turn of the hexagonal spanner, the ratchet can be easily adjusted depending on the load and sailing style.
Versatile mounting:
The Ratchamatic® block can be mounted on both starboard and port sides, offering installation flexibility.

System integration

Ideal for mainsheet and jib sheet:
The block is perfect for use with asymmetric spinnakers and ensures an effortless jibe.
Optimal mainsheet system:
In combination with a switchable ratchet in the cockpit and an additional Ratchamatic® on the boom, you achieve double holding power in strong winds and free running in light winds.
