Description
Harken's Grand Prix systems for high-performance dinghies | such as the Nacra 17 or F18s. The high-efficiency blocks that make up these systems have cast ceramic bearings, | which virtually eliminate rolling resistance, | which significantly improves power transfer to the crew, | allowing for easy and precise trimming. These compact blocks | have hardcoat anodized side plates that encase | composite discs for easy removal / reassembly. | The system profile is by far the lowest on the market. | High-performance fairing increases aerodynamic flow and | protects the crew and blocks from impact damage. The | The lower block has a built-in cam arm that is | infinitely adjustable by loosening two screws. A single | ratchet washer in the bottom block ensures release is | controlled and easy.
