Greenfield Products Dock Lines: American-Made Innovation on the Water

Greenfield Products is not a newcomer to the docking world — they invented it. Founded in 1959 in Greenfield, Ohio, by J. Paul Gessner, this small, family-owned American manufacturer takes pride in its multi-generational record of innovation. When it comes to dock lines, Greenfield occupies a category all its own: they didn't just make a better dock line — they reimagined what a dock line could be.

The Original Bungee Dock Line: Dock Buddy

As the originators of stretch-cordage for boating, Greenfield's innovative bungee products became game-changers for docking small and midsized craft. The Dock Buddy, the world's first bungee dock line, was introduced in the 1990s and soon became a worldwide standard in the docking products category.

The Dock Buddy is an easy-to-use dock line that stretches between a boat cleat and a dock cleat, without knots — a simple slide adjustment tightens the loop around a cleat and allows for quick and secure docking. The loose weave of the polypropylene cover expands when the Dock Buddy is short but tightens and narrows as it is stretched, while the internal bungee cord provides stretch and the polypro cover ultimately limits how far the bungee can extend.

The 4' model stretches to 5½', the 5' model stretches to 7', and the 6' model stretches to 9'. Construction features a bungee cord covered by hollow braid polypropylene, soft foam sleeves for easy gripping, and sliding PVC tubes at the ends for eye adjustment — and if dropped in the water, they float. Dock Buddy is available in colors to match popular boat trims and accessories and comes in three sizes to meet any boat-to-dock need.

Taking It Further: Stretch N' Slide

Greenfield took stretch cordage in a bold new direction and in 2006, introduced the Stretch N' Slide — the world's first bungee loop-line for docking or rafting. This innovative multi-loop design makes the dock line the perfect size every time, eliminating the need for users to choose a specific size.

The innovative multi-loop bungee allows a perfect fit for any span up to 7' — simply place the end loop over a cleat, stretch and tighten down the slider, then select the appropriate loop to place over the second cleat, creating a quick and accurate connection regardless of the distance or elevation between boats. A rafting party can be connected in minutes without tying a single knot, and the shock-absorbing bungee allows an entire chain of boats to move and flex together with ease.
