No, only one dimension I am changing, it is not scale, it is not scale change, is just one
dimension I am changing, I can change l by b, b by t, I can change block coefficient, I can
change LCB by changing (( ))... general nature of form remains same- this is called the series,
developing a series of ships. So, if I generate a number of ships like this and test them in a
tank, what I get is a matrix of ships for which all resistance data is available and if I can
present it properly, then for any intermediate dimension I will be able to tell what will be the
resistance- this was the thought way back in 1950’s, 40’s and 50’s.
