Several tests of the Boatasy GHOOK have been carried out on a variety of boat types. We investigated how the new product reacted to different thicknesses of lazy lines (mooring lines). We were especially focused on mooring operation performance. Our researchers have analyzed different hooks and tested different elements in order to determine the best ratio between the shape of its elements and performance (speed of transfer). Thanks to all of the research that has been carried out, we have succeeded in optimized some details of the wheel and the structure of the handle.
