An apparatus for measuring tensile and bending forces applied to a fat-line towed-array. Tension sensors are configured within a modified fat-line towed-array bulkhead to measure axial tension applied to the front of the fat-line towed-array, while bending sensors mounted further downstream along the fat-line canister interior walls, measure the bending load. The sensor outputs are encoded and digitized before transmitted through a tow line for further data conditioning and processing. The tension and bending sensor data provide information to evaluate the force exerted on the towed-array, allowing a measure of the deployment capability. Measurements taken at various fluid flow rates provide data regarding deployment effectiveness.
