The purpose of this study was to develop learning model turtle boat of teaching-learning materials in order for the students to enhance knowledge, skill and attitude and give interest in transportation technology, and also to recognize the legacy of Korean history. The model turtle boat was developed through three major phases; preparation, development and improvement. The main results of this study were as follows: First, the model turtle boat was developed for students to cultivate design, fabrication, process abilities, and also technological literacy by experimenting and fabricating for themselves. Second, the learning model turtle boat developed is equipped with the sail using natural energy, the linkage and screw applying a mechanical energy and solar cell using solar energy among driving energy. Third, in order to increase interest and attitude regarding a ship in transportation technology, the model turtle boat was developed for students to be able to operate with wireless transceiver on water. Fourth, the model turtle boat was developed to apply the teaching and learning materials for the classes of experiment and practice in primary and secondary schools.

In the present paper, a hull form for the turtle boat type incinerating vessel was developed based on the Finite source Distribution Method(FDM) and 1-$C_p$ method. In order to obtain proper hull form within the limited time and budget, a computer program OCL(Optimization of $C_p$ and LCB) was developed adn used. For the confirmation of the theoretical results by OCL, these theoretical results were compared with results of model test in the circulating water channel (CWC)in Chosun University.
