Although they weren't all a-holes. I've met many lifelong friends diving.
The true answer is that I opened up Cuba for American Flagged commercial passenger vessels. I worked for 10 years to obtain an ABS Load Line on a 40 year old existing vessel, successfully, and I performed all of the engineering and drafting except the hydrostatics. I am a marine and nuclear engineer, not a naval architect. I was the first commercial US passenger vessel to legally make a voyage to Cuba since 1962. I made 2 trips and had 6 on the books, and I was killing it.
Like many Captains, I'm a bit of an arrogant prick. I had an in in Cuba, and all of the support I could ever want if I only followed their rules. As stated, I am a bit of a prick, and I also made some cultural faux pas that I could not recover from. I had been told how to act, but again, I am a bit of an arrogant prick.
I sold my boat for far more than I paid for it, and sold it in Cuba where she is being used exactly for the purpose she was best at, carrying out diving research in one of the most beautiful places in the Caribbean. I have no regrets, I had the best job in the world for 20 years.
