RIB(Rigid Inflatable Boat)형 보트는 선체, 팽차식 선측튜브를 적용한 고속 다목적보트로 뛰어난 내항성능과 높은 안전성으로 해외 선진국에서는 해양레저 활동에 적합한 신개념 고부가가치 보트로 각광받고 있으나 국내에는 레저용 RIB 보트의 제작 및 개술개발 실적이 전무한 실정이다. 이에 본 연구에서는 고속이면서도 안정성 및 편의성을 고려한 레저용 RIB의 최적선형 설계 및 공간배치 연구, 하이파론 선측튜브 설계, 조선학적 제계산을 통한 주요성능 검토 등을 통하여 최근 급증하고 있는 해양레저 수요에 대응한 6m급 RIB형 레저보트를 개발하고자 하였다.

Currently offshore fisheries are one of shrinking industries and fishermen are getting older. Moreover it is difficult to work fisheries for decreasing fishermen as the time goes. Two people per a boat work together at least for proper fisheries. If the unskilled fisherman boards on boat, it will make some troubles to speak each other and diminish the efficiency of working because one person should control the boat. So it need to study the remote control system for leasure and outboard engine that can control and work at the same time. The remote control system is consisted of engine, steering gear and forward reverse neutral gear controls. These three controls are made by position and speed control using DC motor, and microcontroller is used to control the engine speed and rudder angle. This system can be controled and worked alone and we tested the system at sea and confirmed that the system works properly.

In the coastal area, many kind of vessels are operating and exposed to the various marine accidents. In particular, small-size vessels, which are not equipped with the safety equipment, are in the defenceless state to the marine accidents such as the accident according to vessel's own state caused by the diverse reasons and the collision with the neighborhood vessels and objectives. So it is necessary to resolve these situations through the inexpensive equipment. This paper implements the function that can detect vessel's own motion using Smart Phone. if the motion is over the threshold value assigned, this function decides that the current situation is dangerous for this vessel. So this function informs Smart Phone's ower in the vessel and the control center of this situation. This function can be applied to small-size vessels, such as fishing boating, passenger ship, and leasure boat, which have few the safety equipments, and then improve vessel's safety navigation.
