A dolabriform bow high-speed boat model adhered with wave-elimination-damping wings comprises a dolabriform bow, wherein two symmetrically distributed wave-elimination-damping wings are installed below waterlines on two sides of the dolabriform bow. When a boat sails on the peaceful sea surface or in small storm waves, the wave-elimination-damping wings have a wave-elimination effect, and a lifting force is generated on the wave-elimination-damping wings to raise a boat body, reduce contact area of the boat body and water and reduce friction resistance. Simultaneously, waves generated by the wave-elimination-damping wings and boat-shaped waves can mutually generate favorable interference to reduce wave-making resistance. Effects of the two aspects enable traveling resistance of the boat to be remarkably reduced. When the boat sails in large storm waves, the wave-elimination-damping wings have a damping effect on vertical motion of the boat in waves, so that the boat with the dolabriform bow can have small vertical accelerated speed and small vertical motion amplitude, and seakeeping performance of the dolabriform bow boat model is further improved.
