Harken's largest and most versatile range of blocks. Carbo AirBlocks® have become the standard for racing sailors and small boat cruisers. These are 30% lighter and 60% stronger than previous generations, and they're well-suited for the small-diameter, hard line favored today. Carbo blocks come in all shapes and sizes, including, switchable ratchet blocks and load-sensing Ratchamatics®. Today sailors may also choose any Harken Power3 ratchet sheaves in any ratchet block. These sheaves offer different line holding power sailors can perfectly match to the day's sailing conditions.
