Buster Keaton in “The Boat” from 1921. In which Keaton builds a motor cruiser in his basement, launches it, and sets off voyaging with his family, with many tribulations. At the time, motor cruisers were becoming popular among young families like the one portrayed in the film, and magazines such as Rudder and Power Boating were full of plans from which you could build your own. 

Keaton’s boat is named “Damfino”, which I imagine is from “Damn Fine”. Compound words were a common way to name a boat at the time. I was reminded of this film the other day when I ran across a reference to a cruiser called Damfino in a set of race results from the late 20s; presumably that boat was named after Keaton’s fanciful deathtrap. It had not finished the race, which is as to be expected.
