Through building a ships type library by using the presentation of knowledge and encapsulating the digital design functionality of the hull structure by using model library and also using distributed database to manage the ship information, a prototype software system is developed. The system achieves rapid design and modification of the three-dimensional solid model of the ship structure, which is demonstrated with a real ship model. Key words: ship struc
