WDSchock - you may be right. They did get used to relate to adults on a more mature level. They had no choice really!
I think there are a few critical components of cruising with this age group:
1) Making sure the education is covered, which leads to-
2) Keep the geographic area manageable, for instance our kids required internet connectivity on a regular basis (not all the time - we went for a month or so without a few times, but then they definitely needed it) so you cannot chance taking off into an area where that is not going to be possible (unless you can pay thousands for satellite uploads).
3) Find activities they want to buy into but prepare them before; we spent three weeks scuba diving in Bonaire every single day after schoolwork. We bought a second hand windsurfer so in Curacao they windsurfed every single day after school for two weeks. In Colombia we went on a six day jungle hike into the mountains - that sort of thing. In Panama after the isolation of SAn Blas, we spent a few days just hanging out in Allbrook Mall so they could get their "Mall fix".
4) Give them responsibilities
5) Give them a full vote in activities and cruising destinations. Explain changes without forcing it on them.
6) Learn to live with little privacy
7) Be very very tolerant of the inevitable irritations resulting from personal habits.
8) Get off the boat enough.
