I have thought it woudl be a fun "early" retirement job (though I seem to not be getting there on the 401K for the early part) to be able to take dive boats out and and other tour type boats. Would a 100 ton be enough for that? I know I when I went on a snorkel boat tour in Maui, my brothers friend was a part time captain for them, and he seemed to enjoy it. I don't think he really needed to work, he spent half the year in Montana and half in Maui. It was a long term relationship with the tour company and I understand it is not exactly like they are desperate for folks to do the work. But I could start working on the relationship soon enough.
