Harken Cleats
Harken Cleats: Engineered for Instant Control on the Water
When it comes to line management on a sailboat, few components are as critical — or as frequently tested — as the humble cleat. Harken, the Wisconsin-based sailing hardware pioneer founded in 1967, has spent decades refining the cam cleat into something that feels almost effortless under pressure. Their cleats are a natural extension of the same ball-bearing philosophy that made the brand a household name in racing circles worldwide.
The Ball-Bearing Advantage
At the heart of Harken's cleat lineup is a multi-row ball-bearing system that sets them apart from conventional designs. Multiple rows of high-load ball bearings and a precise V-shape channel dramatically reduce friction, allowing the cams to activate with a quick snap of the wrist rather than requiring a full draw-through motion. A downward flick snaps the sheet into the cam cleanly, and a flick upward releases the line instantly — even when it's under significant load. This combination of fast engagement and reliable release is what makes Harken cleats a favorite from dinghy control lines to offshore racing sheets.
Cam-Matic® and Carbo-Cam® Product Lines
Harken offers two primary cleat families to cover the full spectrum of sailing conditions:
- Cam-Matic® Aluminum Cleats: Hardcoat-anodized aluminum construction makes these the go-to choice for high-load, high-wear, continuous adjustment situations. A PTFE-treated surface further improves fast line engagement. Available in Micro, Standard, and Offshore sizes, the popular Harken 150 is a benchmark cleat widely used as a mainsheet cleat on keelboats and larger cruising systems.
- Carbo-Cam® Composite Cleats: Lightweight fiber-reinforced composite construction is ideal for racing applications where every gram matters, or where adjustments are made less frequently. Available in Micro and Standard sizes, these are commonly found on high-performance catamarans and dinghies like the 49er.
Both lines share Harken's signature protective tooth design — rounded teeth that hold lines securely by squeezing rather than cutting into the braid, meaningfully reducing line wear over a season of hard sailing.
From Dinghies to Offshore Racers
The breadth of Harken's cleat range is part of what makes the brand so trusted. The compact Harken 468 remains a staple on smaller dinghies, while the Harken 365 and 150 handle the demands of larger mainsheet and control-line systems. The Micro Cam Base with Swivel is a regular fixture on high-performance racing dinghies and cats. Whatever the platform, there's a Harken cleat engineered to match the load range and adjustment frequency of the application.
For sailors looking to upgrade their deck hardware with components trusted at the Olympic and America's Cup level, Harken's cleats represent one of the most proven choices in marine hardware.
