The Zircon blocks are the most efficient Harken has ever made. The performance is unmatched due to the ceramic ball bearings. With the Zircon blocks the energy loss caused by friction is extremely low. Even lower than the amazing Carbo range from Harken. So especially when the breeze backs off, the Zircon blocks let you ease.
Zircon bearings are more than 700% stronger than stainless bearings. This becomes evident when you need to ease a sail in very light air. You feel even the slightest fluctuations in sheet load.
