In the initial hull form design process, a hull form surface is essential for mesh generation and model ship for hydrodynamic analysis. In the current shipyard, when generating a hull form surface, a commercial program is used to generate the hull form surface by manual work of the worker. As it relies on manual work, there is a different in hull form surface depending on the maturity of the worker. In addition, there is a problem in that variating the hull form requires a lot of time because the hull form surface must be regenerated. Therefore, this paper proposes a method of automatically generating hull form surface from a given wireframe. A method is proposed for generating a suitable hull surface using the Skinning surface, Trimmed surface, Coons patch, and Gordon surface for each compartment. The hull form surface generated using the proposed method was verified by comparing the hull form surface used in the actual shipyard with the results of hydrodynamic analysis. As a result, the quality of the hull form surface was sufficient to generate a mesh for hydrodynamic analysis, and the actual usability in the shipyard was confirmed.
