Collection: Dock Line

Keeping your boat secured to the dock starts with choosing the right line for your vessel's size and your slip's layout. This selection covers nylon dock lines from New England Ropes and Sea-Dog, in diameters of 5/8" and 3/4" and lengths from 15 to 50 feet. The diameter you need depends primarily on your boat's displacement and cleat size, while the length should account for tidal range and how far your cleats sit from the dock. Shorter lines work well for a bow or stern in a tight slip, while 50-foot lines give you reach for spring lines or vessels with widely spaced cleats.

Construction matters when comparing options. Sea-Dog's double braided nylon lines offer a soft, easy-to-handle feel with good elasticity to absorb shock loads from wakes and weather. New England Ropes brings its 3-strand premium construction, which is traditional, easy to splice, and dependable for long-term dock use. Both materials are nylon, which means some give under load, a genuine advantage over stiffer synthetic lines in a floating dock situation. Color choices across black and white allow you to match your boat's deck hardware or meet marina requirements. Measure your existing lines before ordering and confirm cleat compatibility at both the boat and dock ends.
