The stand says "ornament" at first glance. Looking further, the rigging can't work either as an RC or free sailing pond yacht, so the ornament thinking continues. While it appears to have some "proper" fittings (rather than bits of bent wire), I suspect that rather than a model of a specific prototype, it is just a generic item intended to dress up an area near a bookshelf.
A look in a gifts and fancy goods shop might show some similar items, and give a clue to a realistic value, but really, it is worth whatever the eventual buyer is prepared to pay.
