I have a nylon 50-footer that I use on the beach with my guy, same thing, he can run and play but it's almost impossible to call a dog and have the dog hear it with the sound of the ocean and waves breaking
That's where having a remote collar becomes very useful. It doesn't have to be a "shock" collar, it can be one that just vibrates or makes a noise if you otherwise have a dog with excellent recall. I used Perry's e-collar when he was too far upwind to hear me. I would give him a very brief stim at the lowest level he could feel, to get his attention, then use hand signals to tell him what I wanted. Wave him in to recall, or put my hand up palm out to ask him to wait. Worked very well for that purpose.
