According to the present invention, disclosed is a vessel including wave estimation equipment estimating a wave spectrum in real time. The vessel includes: a camera (110) photographing a wave image omnidirectionally; a measurement instrument (120) sensing a motion of a vessel body; and a control part (130) estimating a wave direction through image analysis on the wave image, specifying a specific RAO table corresponding to vessel velocity information and a loading condition of the vessel from an RAO DB, selecting RAO data corresponding to the wave direction from the RAO table, and estimating a wave spectrum of a sailing sea area in real time by analyzing measured motion information and wave direction information estimated based on the RAO data through a specific wave estimation algorithm. Therefore, the vessel including wave estimation equipment estimating a wave spectrum in real time is capable of using a wave spectrum to an economic sailing solution for shipbuilding yards by estimating the wave spectrum increasing the analysis precision of added resistance by waves in real time.
