I lived in Friday Harbor for almost 10 years (after Jay Benford had moved), and always wanted to see one of these "ferries" in real life. I read Jay's books, and love many of his designs. You have built a truly amazing vessel, Whistledoc. As it is hard to "pigeonhole" such an animal, I think you've earned the right to call her whaever you want. The term "riverboat" certainly works for me, as it conjures up a more romantic image of traveling by America's riverways. And your Annie is gorgeous, befitting of both the term (riverboat) and the romantic imagery. Well done!
