Study and Design Sailboat Type Dinghy

Abstract

The Objectives of this research are 1) to study the form of Dinghy boat 2) to design a Dinghy boat by using D Ronald K. Kiss Ship’s Iterative Process on Design Spiral, by studying the model’s data of Dinghy sailboats, including related Ideas, theories, and interviews with the yacht racing association of Thailand’s officers. The Purposive Sampling Method as used. After studied the form of the Dinghy boat, the designing process then started by using collected data, through analytical processes with conceptual framework for product design; The Quality Function Deployment, the Theory of Inventive Problem Solving, the Design Spiral which is an iterative Process, and the Reverse Engineering Principle. The experts from both the fields of Industrial Product Design and Sailing Boat, whom concern Dinghy Boat format, were included to evaluate the designing and model constructing process. The statistical methods used were Percentage, Median and Standard Deviation (SD.). The research found that 1) the current type of Dinghy sailboat is still unsafe for novice sailors; It is difficult for practicing, limited on sailor's weight, very difficult to relocate and take care of, it also were built from the expensive materials 2) In designing, the researcher designed the boat's hull by concentrate on its floating center The middle movement, which would have an effect on its floating aspect, which might tilt the boat, to be straight and highly secure. Researcher designed the parts to be able to disassemble and redesign shapes, and use wood as a material for maintenance purpose in accordance with the technical requirements that expected for Dinghy boat, from the Sailing Boat experts under Yacht racing association of Thailand. In the opinions of the honorable experts, the Dinghy Boat type 1 was scored following these factors; Meet the usage demand of the boat (Mean = 3.88, SD. = 0.33) The determination of size and dimension of the boat (Mean = 4.13, SD. = 0.33) The line pattern and shape of the boat ( Mean = 3.88, SD. = 0.33).
