ABSTRACT:
An oar lock device, comprising a socket member and an oar clamp member. The socket member has a bracket portion and a socket portion. The oar clamp member has a shaft, a shoulder portion and two oar brackets. The shaft is connected to the shoulder portion and rotates within the socket portion of the socket member. The oar is clamped between the oar brackets, which are attached to and rotate about the shoulder portion. The bracket portion of the socket member is attached to a boat. The oar can be rotated about a generally horizontal axis through the shoulder portion, and also can be rotated about a generally vertical axis through the socket portion. A preferred embodiment uses neoprene sealed ball bearings in the socket portion and the shoulder portion to greatly reduce friction and assist with a silent, smooth and rhythmic stroke motion.
