So, I have got essentially local b x, b n and sectional areas. Normally, what happen? Sectional area and the local breadth is a good representation of a ship section, although
you may say that there to be many section, but you will find out that when you do design problem, you actually develop the lines plan based on those two parameters. Essentially, you actually you know like find out the sectional area curve, that is S n curve and a half breadth tan curve, that is b B n curve and based on the two you actually try to find out the section.
