I’m not saying the book is wrong, it’s just that I don’t understand what the benefits are from specifying the location of a point in space relative to a shifting origin point. I was hoping you could quote the paragraph from the book with the definition you are using. (or perhaps paragraph and page number)

I think the big difference is that the book, Principles of Yacht Design, and others (Skene’s Elements of Yacht Design, for example), have their roots in yacht design that was performed in ink on paper. The beginning of such design is always Station 0, where the stem meets the DWL. The books then teach to layout an even number of stations (usually ten, often divided into half-stations) along the DWL. Because of this, the origin point is always fixed at that meeting point of Station 0 and the DWL, as is the station spacing along the length of the DWL. “Midships” is literally Station 5 in a 10-station layout.

This is a point of confusion for me as well, as I am new to Delftship (but not hull design software), and came to the forum in search of answers. I am curious why there is not the choice of using the cutwater as the reference point, as well as to pre-determine station spacing, as other hull design software does.
