Chinook Race Harness Lines provide the ultimate windsurfing harness lines. Easy in-flight adjustment is provided by a heavy duty roller and cleat system. New style Chinook race lines now utilise clear plastic tubing for better shape stability while sailing. Maximum adjustment length can be trimmed or tied to suit. Harness line adjustment range can be reduced by trimming the plastic tubing to almost nothing on the lower range. Harness line adjustment range out of the packet is approximately 24" to 38". Perfect for raceboard sailing and general windsurfer racing.
