A major issue argued between big-wave surfers is the necessity of the leash on the surfboard. In many instances, the leash can do more harm than good to a surfer, catching and holding them underwater and diminishing their opportunities to fight towards the surface. Other surfers, however, depend on the leash. Today, tow-in surfboards are equipped with foot holds (like those found on windsurfs) instead of leashes, in order to provide some security to the surfer without generating safety hazards whilst the surfer is underwater.
