Master Mariner is the official title of someone qualified to command a ship; the qualification is colloquially called a "Master's Ticket".
The term was introduced in the mid 19th century, and is usually held by the chief officer/first mate as well as the captain).
The Master's Mates were the assistants to the Sailing Master, also warrant officers, and were usually young men with family connections not quite good enough to become midshipmen who either aspired to become sailing masters themselves or to be commissioned as lieutenants, as often happened.
HMS Reclaim was despatched to that position and lowered a camera 258ft, which picked out a brass handrail before scanning the bridge to reveal the name Affray.
HMS Affray had been found lying on an even keel near the edge of the Hurd Deep on a bearing 228 degrees and 67 miles from St Catherine's lighthouse on the Isle of Wight.
HMS Reclaim returned to the wreck with X-ray equipment and, after clearing part of the casing, radioactive isotopes were used to see through the hull.
