No starboard won't name their boards after real volume; and no, they won't even quote "real" volume on tech charts. And yes, they are probably 100% aware of real volumes, since the real volumes we read on the ISAF charts are provided by the manufacturers.
Reason for this is that "real" volume is not an accurate indicator of how a board will SAIL, since as we know width has a big importance too. So some customers (intermediates, heavyweights...) will be misguided in their choice, because "real" volume still is THE indicator of how a board will FLOAT. What I don't see, at this point, is why they don't name boards after width instead.
As I said many times before, to me, to provide a "wrong" tech data is a total nonsense.
