Dave,
I'm really not familiar with the program you're talking about, but I can promise you that if you go in, either as an officer or enlisted, the Navy will hold you to the terms of your contract. They will be firm but fair and you will get what you give. If you complete nuke training and serve out your term (and I can only speak for the Sub Service) you will learn to run a nuclear power plant in a way that you'll never be able to learn any other way. It'll be like learning to drive at a Nascar training facility. You'll operate under pressure that can't be duplicated in the commercial world. You'll also go months without seeing your family. You'll go days without sleep. You'll work holidays, nights, weekends and any other time you can find.You'll get kicked in the ass and stabbed in the back. You'll make enemies you want to kill and friends you'll want to adopt. You'll get seasick, homesick, heartsick, sick and tired and 10 thousand other things that will make you want to piss on John Paul Jones. You'll see sunrises and starshows, nightlife and wildlife, foreign ports, maybe exotic islands.....things you'd pay hugely for in civilian life.
With the indignation of youth, I cursed my recruiter a thousand times for getting me into that hellhole of a life, but looking back, I treasure the education, experience and the memories and frequently call him up to go have a beer when I'm back home (he was from my home town).
I don't know you and can't tell you whether or not you would have a rewarding experience in the Yacht Club, that's something you'll have to decide. But I can tell you this....IT IS A FREAKIN' ADVENTURE!!!!!
