Bridgewatchkeepers are trained to an equivalent level of STCW, omitting the cargo/stability aspects. Likewise CQ1 is equivalent to a Masters ticket, without the cargo stuff. It is a policy choice to match the standards that make sense to us.
So strictly speaking we are not STCW ticketed.
What you want is a job on a super yacht.
I watched with horror a video blog made by a crewman on such a vessel while it was transiting the Pacific. His only qualification seemed to be extreme competence with a can of Brasso.
Alone on the bridge during the middle watch (midnight to 4am for land lubbers) he explained that this was his time for refining the playlists on his media player. The only time he came close to seamanship was once an hour when he transcribed the ship's position from the GPS display on to a chart that seemed to cover the entire world. He didn't touch the ship's wheel during the entire watch and I swear he dosed off at one point.
Next day this "officer of the watch" included a segment showing the captain using a sextant to double check the GPS receiver. Our man had never seen or heard of a sextant and he couldn't even pronounce the word astronavigation.
I never served on a merchant ship and it's been decades since I served on any kind of ship but ..... WTF?
No doubt automation has progressed a fair bit since my day but do ships now sail themselves? Would the radar make a noise to wake him up if another ship came close? Is it legal to have completely untrained crewmen standing watch alone on the bridge at night.
