The invention discloses a fish-tail-imitating propulsion device suitable for a small waterplane area catamaran, and is mainly used for the field of boats and ships. The fish-tail-imitating propulsion device comprises a steering engine for supplying the dynamic effect, fish-tail-imitating hydrofoils, springs, connecting rods, rocking rods and pin nails. According to the fish-tail-imitating propulsion device disclosed by the invention, the connecting rods are driven by the steering engine to move, the rocking rods are driven by the connecting rods to move, and the fish-tail-imitating hydrofoils are driven by the rocking rods to move; because the pin nails for connecting the rocking rods and the fish-tail-imitating hydrofoils are eccentrically fixed relative to the fish-tail-imitating hydrofoils, the fish-tail-imitating hydrofoils can swing around the pin nails under the driving of the rocking rods, so that propulsion force consistent with fish tails can be generated.
