Abstract: The present invention seeks to provide a novel load cell which measures the force applied to, for example, an oarlock, without alteration to the boat and with minimal requirements for installation, use and maintenance. The force sensing system comprises (i) a force sensor, (ii) a load member to which a load is applied and (iii) a support member contacting a support, the force sensor deflecting when transmitting a force between the load member and the support member; wherein the load member and support member are concentric tubes and form, with the force sensor, a unitary assembly.
