The handy Shurhold Dock-A-Reni Dock Line Holder makes docking a breeze! When combined with a boat hook (not included) the Dock-A-Reni attachment creates and holds a loop in your dock line so you can easily slide it over a piling. Attaches to any boat pole, allowing you to tie your boat up with ease. Simply clip one end of the rope into the Dock-A-Reni and the rest of the loop over the end of your boat hook and you are ready to go.
