The object of the invention is a boat with improved water movement properties. The boat comprises at least one outer mold (100) and at least one inner mold (102) according to the model of the boat to form a double-shell structure, the molds (100, 102) comprising a first hole (103a) through which closed-cell polyurethane has been sprayed with a high-pressure sprayer to fill the empty spaces (100, 102) inside the molds, and a second hole (103 b) through which air has been removed from the empty spaces during said spraying. The boat comprises a rounded design of the stem (107), a shape of the bottom so that the bottom is widest at the front of the boat (109) to reduce water resistance, and as said spaces filled with closed-cell polyurethane side floats (105) on the sides of the boat to stiffen the hull with said closed-cell polyurethane. Further, the boat comprises a keel part (115) containing heavy material as a keel weight.
