Boat names are a huge pain as we have to find where we may infringe on someone who is already using it. Copy rights, trade marks. Got to make sense, be appealing.
You do not really have to worry about copyrights if you are naming a personal boat. It does not matter if someone is already using it as names and titles are not copyrightable. Trademarks, such as Hobie, are copyrightable of course, but names and titles are not. You could write a book and call it "Gone With The Wind" or "In Cold Blood" and no one could sue you for copyright infringement. However the content is copyrightable, just not the title. Many different movies have the same title and they do not have to pay royalties to the original for using the same name again.
So name your boat whatever you wish without worry, just as long as it is not the name of a line of boats
or a trademark such as "Adventure Island." That would would be a trademark, not just a name. Hobie has copyrighted all its trademarks, but you could name your boat "My Adventure" and it would not matter if Donald Trump had named his boat the very same thing, he could not do a thing about it.
There are hundreds of boats with the exact same name, "Wind Song" for example. I have seen three or four with that name. My sloop, that I sold, was named "Nirvana". I am sure there was many others with that name. It is really no big deal.
