“Guidance on Professional Examinations for Mariners Holding Endorsements as Master 500/1,600 GRT Applying for Third Mate Unlimited Tonnage
The Office of Merchant Mariner Credentialing has published CG-MMC Policy Letter 01-25 titled Professional Examination for Mariners Raising the Grade of Officer Endorsements from Master Less Than 500 or 1,600 Gross Registered Tons to Third Mate of Unlimited Tonnage.
This policy removes the examination requirement for mariners who hold a national endorsement as Master 500 GRT or Master 1600 GRT who are applying for an endorsement as Third Mate unlimited tonnage on the same route.”
I can verify that they’ve “received the memo” about this at the NMC.
