Interesting thread for me, as I am toying with getting a captain's license. When I got my first "yacht" (a Carver 355), I called the Coast Guard to ask if I should get a 6 pack license (as I was moving up from a 19 1/2 runabout)--they LAUGHED at me! I am now within sight of retirement, and considering moving boats as a post-retirement job. As a practicing physician, I currently have no time to "crew", and as a lifelong boat owner, it seems onerous. I recently was told that I can log the time I spend on my own boat as "sea time". I have heard conflicting things about what I can count as a day, and sad to say, nothing in this thread has helped to clear up my confusion! I have been told I can log time spent at the dock (most weekends) as sea time, and also that I can only count time under way. I am a recreational boater, and do go out most weekends, but am seldom underway for 4+ hours, but am often on the water for 4+ hours. Any comments regarding my situation?
