18 in stock

The Ronstan Ratchet Block is a high-performance block designed to reduce sailor fatigue by providing powerful line-holding assistance. Its ratchet mechanism allows high loads to be controlled with significantly less physical effort while maintaining precise handling. Advanced design and ball bearings ensure smooth line flow and efficient release when the ratchet is not carrying maximum load. It is ideal for mainsheets and spinnaker sheets where strong grip, superior durability, and racing-level control are required.

At Saildeck Gear, we specialize in technical rigging, blocks, winches, and deck hardware for boats between 30 and 60 feet. We know that every boat is different: working loads, mast dimensions, the type of maneuver, and how you use your boat—cruising, racing, or charter—all affect what you actually need.

That’s why we don’t publish a fixed price on the product page: we prefer to speak with you first.

Tell us which product you’re interested in and which boat you’ll be installing it on, and we’ll prepare a quote tailored to your setup, including technical advice and with no obligation.

If you have any questions about compatibility, measurements, or which part is right for your rig, you can also contact us here. We normally respond within 24–48 hours.

The information you provide will be used solely to respond to your inquiry. Please see our Privacy Policy for more information.
