Experimental studies of the proposed device showed that the magnitude of the measurement error of the stop on the shaft of a moving vessel, provided that strain gages of similar characteristics are used does not exceed 4–4.5%, this makes it possible to measure the stop on the shaft during full-scale tests of vessels without prior bench calibration shaft.
