This report supersedes B.S.R.A. Report NS. 101 and presents all the available ship-model correlation data obtained under the joint B.S.R.A.-N.P.L. programme up to January 1973, together with additional data correlated at Vickers Ship-Model Experiment Tank, St. Albans. The data, which are arranged in three parts, are presented in a similar form to that adopted for the earlier version, B.S.R.A. Report NS. 101 dealing with this subject.

The classification and grouping of the data are briefly described and references are given to papers dealing with the analysis of the data and methods of deriving performance prediction factors.
