Let’s Talk About Harken 40mm Carbo Air Pivoting Lead Block w/Aluminum Cam-Matic Cleat
The Harken 40mm Carbo Air Pivoting Lead Block w/Aluminum Cam-Matic Cleat is a seemingly small component that can make a huge difference in sailing performance and ease of use. Harken is a well-respected name in the sailing world, known for producing high-quality, durable, and innovative hardware, and this block appears to be no exception. Its pivoting feature combined with an aluminum Cam-Matic cleat promises versatility and secure line handling, all in a compact package.
My journey to this particular block started with a frustrating experience on my own small keelboat. The old, fixed lead blocks were creating excessive friction and making it difficult to adjust the jib sheets smoothly, especially in gusty conditions. I needed a reliable solution that would reduce friction, offer secure cleating, and adapt to changing angles, leading me to research pivoting lead blocks with integrated cleats.
Upon receiving the Harken 40mm Carbo Air Pivoting Lead Block w/Aluminum Cam-Matic Cleat, my initial impression was positive. The block felt solid and well-constructed, with a smooth, almost silky feel to the sheave rotation. The aluminum Cam-Matic cleat looked robust and capable of securely gripping lines, even under high loads.
I considered several other options, including similar blocks from Ronstan and Lewmar, but ultimately chose the Harken block due to its reputation for durability and smooth operation. The Harken block also appeared to have a slightly more refined cleat design. My initial excitement stemmed from the promise of smoother sailing and more responsive control, potentially eliminating the annoying friction and jerky adjustments I had been struggling with.
Real-World Testing: Putting Harken 40mm Carbo Air Pivoting Lead Block w/Aluminum Cam-Matic Cleat to the Test
First Use Experience
I first tested the Harken 40mm Carbo Air Pivoting Lead Block w/Aluminum Cam-Matic Cleat on my 22-foot keelboat during a weekend sailing trip on a local lake. I used it as a lead block for the jib sheets, replacing an older, fixed block.
The performance was immediately noticeable, even in light winds. The pivoting feature allowed the block to align perfectly with the sheet angle as I trimmed the jib, significantly reducing friction and making adjustments effortless. The Cam-Matic cleat provided a secure grip on the line, holding the sheet firmly in place without slippage.
The ease of use was outstanding, requiring no time to get used to. Even in wet conditions, with spray coming over the bow, the block continued to perform flawlessly. There were no unexpected issues or surprises during the initial use.
Extended Use & Reliability
After several months of regular use, the Harken 40mm Carbo Air Pivoting Lead Block w/Aluminum Cam-Matic Cleat has proven to be incredibly reliable. There are no signs of wear and tear, despite being exposed to sun, saltwater, and occasional rough handling.
The block continues to rotate smoothly and the cleat still grips lines securely. Cleaning is simple, requiring only a quick rinse with fresh water after each sail. Compared to my previous experiences with fixed blocks, the Harken block provides a significantly superior sailing experience, offering smoother, more responsive control and improved overall performance.
