Entry & progression
There is a second way in, and it bypasses the entire yacht ladder. If you already hold an MO71 Master <500 GT or an MO71 Chief mate <3000 GT, you can go straight to Master <3000 GT (Yachts) — no yacht Watchkeeper, no yacht Master <500, no diploma.
The table as AMSA's yacht page publishes it
| MO71 certificate held | Conditions | MO74 certificate that could be issued |
|---|---|---|
| Deck watchkeeper <500 GT | sea service + separate orals | WK deck <3000 (Y) or Chief mate <3000 (Y) |
| Mate <500 GT | sea service + separate orals | WK deck <3000 (Y) or Chief mate <3000 (Y) |
| Deck watchkeeper | sea service + separate orals | WK deck <3000 (Y) or Chief mate <3000 (Y) |
| Chief mate <3000 GT | sea service + separate orals + ECDIS | Master <3000 GT (Yachts) |
| Master <500 GT | sea service + separate orals + ECDIS | Master <3000 GT (Yachts) |
Look at the bottom two rows. An MO71 Master <500 GT — a ticket a great many merchant and offshore officers already hold — meets the sea service, sits a separate orals examination, holds ECDIS, and is issued the top yacht certificate. This is by far the fastest route to command of a superyacht for anyone already in the merchant system, and it is badly under-used because almost nobody in yachting reads MO71.
CAUTION — Two AMSA pages publish contradictory mappings. Neither is picked here. The table above is from AMSA's Yachting qualifications essentials page. AMSA's Career path for master and deck page publishes the same table with different mappings — it maps Mate <500 GT and Deck watchkeeper only to Chief mate <3000 GT (Yachts), not to Watchkeeper deck as well.
We are not going to resolve that for you, because we cannot. Two official pages of the same regulator disagree. Before you plan a career around any row of this table, write to AMSA and get the mapping confirmed in writing for your specific certificate. An assessment letter that says something different from the page you read is not a surprise you want after you have resigned a job.
And the quieter route: you may not need to convert at all
MO74 s7(b) is worth knowing by heart. It permits a person to perform the Schedule 1 duties on a yacht while holding a seafarer certificate of a grade mentioned in Schedule 1 of Marine Order 71 that permits the holder to perform the duties or functions.
Read plainly: an MO71 ticket of the right grade lets you work the yacht without converting to a yacht ticket at all. The MO71 route in the table is about obtaining an MO74 certificate. Section 7(b) is about doing the job. Many merchant masters who move into yachting never need the yacht certificate; they need the job, and their existing certificate already permits it.
So there are three questions, and people routinely collapse them into one. Can I do the job? (s7(b) may already say yes.) Do I want the yacht certificate? (Then the table, or the ladder.) Which does my employer, my flag and my insurer actually require? That third one is answered by your DPA, not by a Marine Order.
