The article is concerned with the conceptual modeling of multifunctional hydrofoil vessel “Afalina”. The review of analogs is represented and the basic characteristics of this type of vessels as well as their multitasking functionality are described. The search of lines is carried out on the basis of biological prototypes and the searching process is illustrated by the variants of rough drawings. The vessel drawings are designed on the basis of chosen rough drawing; the constructional features and ergonomics of different modifications are described. The methods and tools of three-dimensional computer modeling are selected; shading and rendering stages are represented. The settings of multifunctional hydrofoil vessel rendering are obtained in the course of engineering.
