Continued full scale wave and stress measurements were conducted on a 1000 ft. Great Lakes ore carrier, the MV STEWART J. CORT to increase the 1979 trials data base. The need for a larger data base was decided based on the limited agreement of results between the full scale data compiled from the 1979 trials and analytical predictions. As part of the 1981 trials effort a hull girder calibration was performed which came within 10 of the expected results. A check of the calculated neutral axis showed very good agreement with the neutral axis location of the calibrated stresses. Limited funding prevented all of the data from being analyzed, except for the hull girder calibration which is presented. This report is therefore a summary of the 1981 springing response trials with descriptions of the changes made since the 1979 trials, the data runs taken, and a discussion of the hull girder calibration. No trails data, except for the hull girder calibration, -is presented.
