Harken GP Catamaran Mainsheet System

Harken's Grand-Prix Catamaran mainsheet systems are critically important options for high-performance beachcats like the Nacra 17 or F18s. The high-efficiency blocks making up these systems feature insert-molded ceramic bearings that almost eliminate rolling resistance, greatly improving power transfer to the crew for easy, precise trimming. These compact blocks feature hardcoat-anodized sideplates that envelop composite sheaves for easy disassembly/reassembly. The system profile is the lowest on the market by far.
