Interpretation:
A recorded stage, expected year, expected date or
delivery statement reflects the latest information
held in the Superyacht Guide record.
A passed expected date without an actual milestone
should trigger re-verification; it should not
automatically be described as an official delay.
Builder pipeline counts represent only public project
records in this database.
