The Ronstan Series 20 Lead Block and What It Taught Me
The Ronstan Series 20 Lead Block is a seemingly simple piece of sailing hardware, yet it plays a crucial role in optimizing sail control. Manufactured by Ronstan, this lead block features a single pivoting sheave designed to guide halyards and other control lines with minimal friction. I first encountered the Ronstan Series 20 Lead Block while working on a refit project for a small sailboat, and its compact design and smooth operation immediately caught my attention.
I was looking for a low-profile solution to lead control lines from the mast base to the cockpit. Space was at a premium, and I needed something reliable and efficient. Other options included traditional cheek blocks and more complex multi-sheave arrangements, but the Ronstan Series 20 Lead Block stood out for its simplicity and pivoting action.
Upon unboxing, the Ronstan Series 20 Lead Block felt solid and well-built. The UV stabilized Acetal sheave rotated smoothly, and the Grade 316 stainless steel load housing inspired confidence. My initial thought was that this was a high-quality piece of hardware that would perform reliably under demanding conditions.
Compared to some cheaper blocks I’ve used in the past, the Ronstan Series 20 Lead Block felt significantly more robust. The pivoting feature also seemed superior to fixed cheek blocks, offering greater flexibility in line routing. I chose the Ronstan Series 20 Lead Block over other options because of its combination of quality construction, pivoting action, and compact size. I was excited to see it in action and assess its real-world performance.
