This Harken Clew Hook and Block system is designed for Lasers and other loose-footed dinghies. It installs permanently on the boom and allows you to easily attach and adjust your sail in high wind and waves.
This set up comes with the clew hook and 16mm AirBlock, already connected.
Works well with the updated Laser clew system. Just run the outhaul line and tie the clew tie-down as usual.
