Boat-tie (or boat tie boat, or boat on boat) is a small still life whose name is a pun on "bow tie" and is a combination of two boats. It can evolve naturally from a formation of two T-tetrominoes.


Boat-tie is the twentieth most common still life in Achim Flammenkamp's census, being less common than Integral sign but more common than snake.[1] It is also the twenty-seventh most common object on Adam P. Goucher's Catagolue.[2]
