Smart ratchet control with added versatility

Ideal for performance dinghies and small keelboats, it transitions seamlessly between free-spin and ratchet modes based on load, offering responsive handling and grip exactly when needed. Lightweight and durable, it’s perfect for mainsheet and spinnaker systems requiring extra control and custom rigging options.
