The present invention discloses a high-density board glass steel ship model and a manufacturing method thereof. The ship model comprises a body, FRP cladding layers, a putty coating layer and a paint coating layer. The body is a high-density board ship model body; the body is composed of longitudinal skeletons, transverse skeletons and waterplane boards; and the outer side of the body is sequentially provided with the FRP cladding layers, the putty coating layer and the paint coating layer. According to the invention, the high-density board is used as the body material of the ship model, and the material is inexpensive and easy to obtain, so that the manufacturing cost of the ship model can be reduced; and the texture is uniform, so that the automatic machining is convenient, and the processing efficiency can be improved. According to the ship model, a combination of the high-density board ship model body and the FRP cladding layers is adopted, so that not only is the strength of the ship model increased, but also the waterproofness is improved. The components of the high-density board ship model (the longitudinal skeletons, the transverse skeletons and the waterplane boards) are automatically machined by using two-dimensional mechanical cutting equipment according to the hull profile drawing, so that the accuracy of the ship model profile can be ensured.
