A catboat (alternate spelling: cat boat), or a cat-rigged sailboat, is a sailing vessel characterized by a single mast carried well forward (typically near its bow). Generally a catboat has a light and shallow draft hull, wide beam approximately half its length, is gaff rigged, and carries a centreboard.
