Automatic and Manual Ratchet Modes
The Series 55 Orbit Block is uniquely designed with both automatic and manual engagement modes, offering unparalleled flexibility in sail handling:
- Automatic Mode: The ratchet mechanism engages automatically when load is applied and disengages when released, allowing the sheet to run out smoothly and freely. This is ideal for rapid easing of sheets and gybing asymmetric spinnakers.

The advanced sheave design includes:
- 12 Gripping Faces: Directly resist loaded line movement for enhanced stability.
- Straight Resistance Faces: Distribute load evenly and minimize rope wear.
- Offset Faces: Draw the rope down into the gripping area under load, ensuring secure line handling.
This innovative design not only improves holding power but also extends the lifespan of your ropes by reducing wear and tear.
