Harken 40mm Single Zircon Block

Description

Get ready for the ultimate sailing experience with the Harken 40mm Single Zircon Block! Crafted with industrial ceramic ball bearings mounted inside caged races, these blocks are designed to give you the smoothest and most efficient small boat block experience ever. With the Zircon blocks, you'll feel acceleration first, before the apparent wind increases and even before the instruments respond. This means you'll be the first to know when the pressure decreases, and you can adjust sail shapes accordingly to new conditions immediately.
The Zircon blocks are available in a 40mm single block and are perfect for jib sheets, spinnaker sheets, and mainsail sheets. Their ceramic ball bearings are more than 700% stronger than stainless bearings, making them incredibly durable and reliable in all conditions. The cages keep these bearings separated so they don't bunch up, touch, or stop each other, resulting in the most efficient small boat block Harken has ever made.
Better sail shape is often the difference between winning and not, and with the Zircon blocks, you'll have an unmatched advantage. The energy loss caused by friction is extremely low, even lower than the amazing Carbo range from Harken. This means that especially when the breeze backs off, the Zircon blocks let you ease with ease. Precision trimming is also a breeze with these blocks, as they are incredibly efficient, allowing you to adjust the sail and sheet tension perfectly.
