Let’s Talk About Ronstan Series 15 Ball Bearing Block
Sailing, like any pursuit involving mechanical advantage and the elements, demands reliability and efficiency. The Ronstan Series 15 Ball Bearing Block promises just that, offering a lightweight and compact solution for various control line applications. Its diminutive size belies a design focused on minimizing friction and maximizing performance, making it an intriguing piece of kit for any serious sailor.
I was drawn to this block as I’ve been upgrading the control lines on my dinghy. I was looking for something compact and efficient to replace some older, bulkier blocks. Initial impressions were positive: the Ronstan Series 15 Ball Bearing Block felt surprisingly solid for its size.
Compared to some cheaper, plain bearing blocks I’ve used in the past, the Ronstan Series 15 Ball Bearing Block immediately felt smoother and more refined. I also considered a Harken Micro Block, but the Ronstan seemed more robust for the intended application. My first impression was one of cautious optimism; excited by the size and build, but curious to see how it would hold up under the rigors of real-world sailing.
Real-World Testing: Putting Ronstan Series 15 Ball Bearing Block to the Test
First Use Experience
I first tested the Ronstan Series 15 Ball Bearing Block on the vang system of my Laser dinghy in moderate conditions (10-15 knots of wind). The difference compared to my old block was immediately noticeable, with smoother vang adjustments and less friction overall. The block ran smoothly even when the line was heavily loaded.
I also tested it in slightly wetter conditions where spray from waves was constant. The Ronstan Series 15 Ball Bearing Block continued to perform flawlessly, with no noticeable degradation in performance. It was easy to handle, and the small size didn’t get in the way. I was very pleased with the performance in these real-world scenarios.
Extended Use & Reliability
After several weeks of regular sailing, the Ronstan Series 15 Ball Bearing Block has held up remarkably well. There are no signs of significant wear and tear. The stainless-steel cheeks show no signs of corrosion.
Maintenance has been minimal; a quick rinse with fresh water after each sailing session is all it has required. Compared to my previous block, which started to seize up after a few weeks, the Ronstan Series 15 Ball Bearing Block has exceeded my expectations in terms of durability and low maintenance. It feels like a significant upgrade to my dinghy setup.
