I don't know personally, but I've heard you can make some alright money as a commercial mariner. Add to that spending weeks or months at sea, still getting checks, but with really nowhere to spend it and you can save up a nice chunk of change, I'm sure
Where I've seen (non-mil) sailors post most often is on /g/ in various IBs. Literally every time they're asking about:
>laptops (self explanatory)
>where to DL manga/doujin (causes inevitable thread fracas)
>data storage (for holding lots of animu/vidya)
>sat internet (most all ships nowadays have internet, but service can be sporadic such as in the middle of nowhere, during a storm, or if the ship needs to use the net for something important; also theres probably 50 other guys trying to use it)
Lastly, you should probably ask yourself how well you do with a disciplined environment. If shit needs doing it needs to get done NOW. Much of my family is Navy, and those whove transitioned or had friends who transitioned to private sector said it's easi-er, but not necessarily easy. Theres also LOTS of Filipinos in shipping, and they're not JUST workoholics, they can make coal miners look like toddlers in a sandbox. Food for thought.
Whatever you decide, good luck and Poseidon protect ye.
also, stay the fuck out of Hormuz, holy shit does your question have the fuckiest timing, lol
