If you go back to the first tall ship race in 1956 you will see the people who organized the race saw it was very popular and formed a new organization. From there the whole tall ship genre has seen quite an evolution but somewhere in this loose classification that now exists was, most likely, profit motive.
For me, a tall ship is a large, square-masted sailing vessel like the one Cap'n Jack Sparrow and his crew sail.
No! Not that boat!
