I just wanted to add that my experience with sailors is they like being at sea. They like doing stuff on the ocean. They like going to interesting places. They like having a sense of purpose. In fact, what really astonished me in my career was when we went to the Gulf. We were in a very hot place, a very dangerous place for six months, with very few port visits, but this crew was amazing. I couldn't irritate them. These guys were doing their business, and for sailors to go to sea and do their business is very important for them, for their own sense of self-worth, self-actualization.
Equally, though, there's another piece. In another ship I was in, when you get to the end of the fiscal year, if you don't have a ship that has a program, then guess what happens? You run out of money and the first thing to get clawed back is the fuel budget. So the fuel budget is clawed back, you have a program, and guess what? In January, February, and March you're probably not doing anything simply because of what is an insignificant amount of money, really; but it's significant in the sense that the envelope that it's in is unavailable, and you have to cancel things at the last minute.
