There are two O-2 billets on a NAG 110', XO and OPS.
Any time you have your own cutter, it's good. Would you rather be the man, or the man's right hand man?
I would rather be the CO of an 87' than XO of 110'.
Some, not too common, went afloat for their first tour, were XO or OPS on a NAG 110' for a year, and then returned to be CO of an 87'. That's a lot of afloat, and I wouldn't call it common, but it has been possible. By the end of that, you will have your permanent cutterman's pin.
Then, maybe go to grad school or a staff tour. You're a mid level O-3 at that point, and pretty soon ready to take command of a 110'.
