Prespliced docklines. Choose from a selection of premium quality, double braid dock lines (available in black, blue, and red). Each line has a professionally spliced 12รท eye. Available in a variety of diameters from 10mm to 16mm and in lengths from 15ft to 35ft. How much line do you need? The size and type of line you use will depend on a number of factors including the size and weight of your boat. In general, lengths for fore and aft dock lines are usually two-thirds of the boat length, and spring lines are usually equal to the length of the boat.
