Abstract

The Domestic boat has been manufactured by hull form of typical foreign boat. In this study, design environment for polyethylene boat is analysed to create new hull form of the boat and design elements are extracted from existing boats and consumer preferences. Key elements in polyethylene boat design are three words "semi-classic, urban and sporty". Hull resistance and engine power for new developed boat can be expected by Orca 3D program. This result indicates that engine power of the boat is much less than that of commercial boat.

플레저 보트 선체는 주로 비강도가 큰 FRP로 제작되고 있으나 2000년대에 들어오면서 FRP 선체에 대한 환경오염 및 해양안전에 관한 법적 규제가 강화되고 있어 FRP가 선체재료로서의 활용도가 감소되고 있다. 폴리에틸렌 선체는 FRP 선체의 단점을 보완하면서 가격도 염가여서 차세대 플레저 보트 선체 재료로 거론되고 있다. 개발 폴리에틸렌 보트의 최종 선형은 개발 보트를 둘러싸고 있는 설계 환경과 개념을 분석한 결과 도시적 이미지의 샤프한 선형이었다. 또한, 선형 설계에 필요한 외형 주요 치수는 기존의 실적선을 기초로 결정한 결과, 전장 5.9m, 빔 2.3m, 형심 1.3m 흘수 0.6m이었다. 개발 보트에 대한 선형 디자인한 후 Orca 3D로 엔진 출력을 예측한 결과 개발 보트는 최대속도 30노트에 대하여는 60kW의 엔진이 필요하다. 한편, 활주상태에서 최소 총저항을 나타내는 엔진출력은 28.5kW이고 선속은 19노트로서 설계속도 25노트보다 낮은 속도에서 운전되어져야 보트를 경제적으로 운영할 수 있다.
