Can someone clarify this for me: what is the definition of maximum section when determing max section area (Ax) and its corresponding coefficient (Cx)? It seems like it's one of the following:
1. The section with the maximum waterline beam.
2. The section with the maximum underwater area.
These two positions are likely to be near each other, but not necessarily so. I haven't been able to find a clear definition of which it is. Can someone shed some light on this?
