The Ocean Theory Certificate (now referred to as Unlimited) is not required for the MCA NOE. IYT has not been required to or produced the Ocean theory certificate for many years.  The MCA approved the current process of completing a sextant competencies checklist during the course using the sextant eliminating the need for passage plan/ocean crossing.  If the MCA has notified you that this document is missing from your submission please remind them of this change which was approved by the MCA.  There are personnel in the MCA who must be referring to an old document as we have this question often.  If they do not accept this reply and you are still having issues please let us know.
