APPENDIX D 



NUMERICAL EXAMPLE OF USE OF SERIES 60 CHARTS 



In order to illustrate the use of the Series 60 Charts in preparing lines plans and 

 power estimates, a numerical example is worked out in this appendix. 



The design chosen is that of a ship corresponding in main dimensions with SCHUYLER 

 OTIS BLAND. It was selected because a model of the resultant Series 60 equivalent of this 

 ship had been made and run, as described in the report, so that actual model data are avail- 

 able for comparison with the Series 60 estimates. 



The principal particulars of SCHUYLER OTIS BLAND as built are given in the first 

 column of Table Dl.
