Ronstan 6:1/3:1 Two-Speed Mainsheet System – Upper Blocks Only

19 in stock

A Ronstan two-speed mainsheet system that lets you switch between a fast, low-ratio purchase for quick trimming and a high-ratio purchase for fine-tuning under load. A ratchet takes much of the load off your hand, and the spring-loaded lower block keeps the system upright and aligned – ideal for dinghies and catamarans. This listing comprises the upper blocks only.

At Saildeck Gear we specialise in technical rigging, blocks, winches and deck hardware for yachts from 30 to 60 feet – and we know that every boat is different. Working loads, mast dimensions, deck layout and how you sail (cruising, racing or charter) all change what you really need.

That’s why we don’t publish a fixed price on the product page: we’d rather talk to you first.

Tell us which product you’re interested in and which boat it’s going on, and we’ll prepare a quote tailored to your set-up, with technical advice included and no obligation.

If you have any questions about compatibility, dimensions or which part is right for your rig, you can also get in touch here. We normally reply within 24–48 hours.

The information you provide will be used solely to deal with your enquiry. Please see our privacy policy for more information.
