What Are Oarlocks and Sockets?
An oarlock — also called a rowlock — is a brace that attaches an oar to a boat, acting as a fulcrum when the boat is rowed. The socket is the permanent fitting mounted to the gunwale or gunnel of the boat, while the oarlock (or horn) is the pivoting piece that holds the oar shaft in place. Together, they form the mechanical heart of any rowboat, dinghy, or tender, converting a rower's muscle power into efficient forward motion.
Why Oarlocks and Sockets Matter
As more boaters venture farther from shore using gasoline-powered engines, a reliable set of oars — and the hardware to use them — is a critical safety backup. If you find yourself in a lifeboat or dinghy, a good set of oars and the ability to use them will greatly increase your chance for survival. For day-to-day use, many boaters also rely on rowboats to get to and from their primary craft moored offshore — these boats require maintenance, and over time their hardware can pit and corrode. Replacing worn oarlocks and sockets with quality hardware keeps your vessel safe and ready.
Types of Oarlocks and Sockets
Understanding the different styles helps you choose the right combination for your boat:
- Horn (Open-Top) Oarlocks: The horned oarlock is an open-topped style that allows the oar to be removed easily — important when coming alongside a boat or pier.
- Round (Closed) Oarlocks: Round oarlocks stay on the oar once leathers and buttons are applied, and are more common for leisure rowing.
- Socket Mount Styles: Oarlock mounting options include top, angle, side, and edge mount. Top mount sockets offer a strong mount and attach to the top of the gunwale, while angle mount and side mount are attached to the side of the gunwale.
Materials: Choosing for the Marine Environment
The market is full of brass and nickel-plated oarlocks and sockets, but for the corrosive maritime environment, bronze and stainless steel are the preferred options. Galvanized steel offers a more economical option for lighter-duty use, while injection-molded nylon is lightweight and corrosion-resistant for casual applications. When replacing oarlock sockets, be sure to check the shaft diameter, oarlock material, and decide whether you prefer open-top or closed-round styles — and when replacing the socket, confirm the shaft size, screw spacing, and material for the perfect fit.
