While studies on theoretical wave resistance have been continuing, it appears that the current state of the art does not provide a sufficiently accurate and flexible method for design office use. To satisfy this need for the British shipbuilding industry a study was undertaken to produce a semi-empirical method. The basis of the method has been taken from thin ship theory. Certain modification has been made to overcome some inherent inaccuracies within the formulation. The resulting formulae were further modified through a regression analysis based on a data base established from BSRA methodical series test results and some Japanese and German data. Recently, a more homogeneous data base has been set up as a part of the NSMB Co-operative Research Activity which led to additional modifications in the formulations. This note describes the original BSRA method development since the latter is still in the process of being validated.
