You have a very good point! I might use that as an insult whenever a passenger bothers me in the future.
Every industry in the maritime business has its benefits. It's up to you to decide which one you like the most and where you want to sail.
Also the Cruise industry has its benefits. You have more time to go ashore and do sightseeing than on a freighter. Cruise vessels also visit populair places that the quays where you are loading/discharging with a freighter. You don't have to cross the north Atlantic during wintertime, cruise vessels sail most of the time in the areas where its nice weather.
What i dont like about working on a cruise vessel, is the way of life there. For example the uniform, i would hate it. In my opinion there is also a 'ahh look at me culture' overthere. Also the fact that the bridge team consist of 4/5 people on 1 watch. What the heck, when i'm taking the dogwatch (00-04 or 00-06) i dont want anyone to annoy me. Go away! But i never would call the Cruise industry dull.
The best thing i like on a freighter is that we are compleetly self supporting as soon as the pilot leaves the ship. No one looking over your shoulder, your on your own at sea. Every one is doing their own thing. There is almost a serenity on board.
