Boat Builders is a Mickey Mouse short released 25 February 1938.
Summary
Mickey Mouse, Donald Duck and Goofy build a boat from fold-out parts, which they name Queen Minnie. The instructions simply say "All you do is put it together" and "Even a child can do it." Donald paints the rudder which Mickey keeps turning, and Goofy thinks the figurehead is an actual woman. As they are ready to set sail, Minnie christens the boat with a champagne bottle, and the boat collapses.
