The Harken 2638 40mm Air Double Swivel Block is a versatile and high-performing sailing accessory designed for optimal sail control in various sailing conditions. This block combines the functionality of a double swivel with the efficiency of an air-assisted secondary sheet system, making it an excellent choice for sailors seeking maximum control and ease of use.
The primary feature of the Harken 2638 Air Double Swivel Block is its double swivel design. Swivels are essential for reducing friction and twisting in the sheet system, which can lead to wasted energy and difficult sail trimming. The double swivel design allows the block to move in multiple axes, enhancing the efficiency of your sail control system.
Furthermore, the Harken 2638 Air Double Swivel Block comes with an air-assisted secondary sheet system known as the AirCam. This system utilizes air to reduce the load on the sailor when trimming the sail, resulting in less effort required and more precise control. The AirCam is easily adjustable with a quick-release system, allowing you to tailor the level of assists to your personal preference.
Made of high-quality marine-grade aluminum, the Harken 2638 Air Double Swivel Block is durable and resistant to corrosion. Its flush-mounted design allows easy integration into the sailboat, resulting in a smooth look and improved aerodynamics. Additionally, the block is equipped with Harken's barrel design, which ensures proper sheave alignment and reduces the risk of wear, extending the lifespan of the block.
The Harken 2638 Air Double Swivel Block is compatible with 40mm lines (sold separately) and comes with an easy-to-install mounting kit, making installation a breeze. Whether you're an experienced sailor looking to upgrade your existing sail control system or a beginner seeking to maximize your boat's performance, the Harken 2638 40mm Air Double Swivel Block is an excellent investment that will enhance your sailing adventures.
