An extraordinarily talented painter and sculptor, and surprisingly, a completely land-based person, Nikolai Vatagin devised and, with a profound understanding of the subject and a healthy sense of humor, illustrated a wonderful children's encyclopedia about people and devices directly related to water spaces. The book, without exaggeration, encompasses the marine theme. It includes everything that floats on water – from kayaks and surfboards to giant bulk carriers, icebreakers, and battleships. It includes everything that floats under water – from bathyscaphes to submarines. It includes everything that flies over water – from firefighting seaplanes to vertical takeoff aircraft launching from an aircraft carrier. There are illustrations explaining how a port and shipyard are arranged. There is a ship in cross-section with detailed images of its numerous compartments: cabins, bridges, holds, etc. There are all those who are directly related to this vast water industry: sailors, divers, designers, oceanographers, etc.
