The Boat is a 1921 American two-reel silent comedy film written and directed by and starring Buster Keaton. The International Buster Keaton Society takes its name, The Damfinos, from this film.

Plot:
Buster is married with two children (both of whom wear the porkpie hat made famous by Keaton). He has built a large boat he has christened Damfino inside his home. When he finishes and decides to take the boat out to sea, he discovers it is too large to fit through the door. Buster enlarges the opening a bit, but when he tows the boat out, it proves to be a bit bigger than he estimated, and the house collapses, utterly.
