APPENDIX B 



USE OF CONTOURS AND CHARTS 



In order to make the data derived from the very extensive Series 60 research project 

 readily a\ailable and useful to naval architects, they have been presented wherever possible 

 as design charts and contours. From these the designer can very quickly make an estimate 

 of performance for any normal single-screw merchant ship whose proportions fall within the 

 area covered by the series. 



The essentia! data are shown in the following figures and tables:
