교통안전특정해역 내 통항선박과 어로에 종사하는 선박간의 충돌 위험성이 높아, 해상교통관제사 및 항해사에게 많은 위험부담이 있으므로, 인명 및 충돌사고를 미연에 방지하기 위하여 해사안전법상 교통안전특정해역 안에서의 항로지정제도를 시행하는 구역에서 지방해양수산청과 지방해경서 간의 어로행위 단속 주체를 관련법령을 통해 명확히 하고자 한다.

어선의 해양사고 중 가장 많이 발생하는 충돌사고의 경우 선박 운항자의 졸음 등의 이유로 경계를 소홀이 하여 발생하는 경우와 어로 작업 중 접근하고 있는 상대선을 발견하고도 어로 작업 특성상 조종성능이 극도로 제한되어 적절한 피항 동작을 하지 못하여 발생한 경우가 대부분이며 이는 성어기의 어선 조업 특성상 선박의 조종업무를 수행할 수 있는 선장의 업무과중에 의한 피로누적과 어로 작업 특성상의 조종성능제한에 의해 기인한 것으로 판단되어 동해지방해양안전심판원 관할구역 내에서 주로 행해지는 자망, 채낚기, 기선저인망, 동해구 트롤어업의 조업 형태에 따른 어선 선원의 작업 여건과 각 어업별 어로 작업 중인 선박의 운항 성능에 대해 알아보고 충돌사고 방지를 위한 대책을 제안하고자 한다.

국내외적인 어업환경 변화 및 1997년 7월 수입자유화조치 이후 우리나라 수산물 소비행태변화에 따라 전체어업에 종사하고 있는 어선의 조업패턴과 수요량도 크게 변모하고 있다. 이와 같은 변화된 여건하에서 국내 연안어업의 실태와 어선건조물량의 분포 및 어업기술 연구개발사례 등을 살펴보고 어선의 수급에 대한 전망과 조업방법의 자동화 방향을 추정하였다.

This study aims at reviewing first the cases of marine accidents of small fishing vessels and vessels towing and being towed and, the problems concerning such lights and shapes that could be misunderstood for those in concerned Rules, or that could impair their distinctive characteristics or obstruct to keep a proper look-out. And then I wish to make a suggestion of the necessity of amending the National Laws which stipulate the rules for the ship's lights and shapes as follows; Firstly, by amending the "Standard of Construction and Equipment for the Less Than 10 Gross Tonnage of Small Fishing Vessels" small fishing vessel must be equipped with the lights and shapes that are the same as those of "vessel engaged in fishing" prescribed by Rule 26 of the "COLREG 1972" and Rule 84 of the "Maritime Safety Law Act". Secondly, "Standard of Fishing Vessels Equipment" which stipulate the rules concerning the exception of the running lights and radar reflector for the small fishing vessels must be amended to meet the requirement of Rule 20 of the "Maritime Safety Act". Thirdly, the definition of "Length of the tow" which prescribed by Rule 2 of the "Maritime Safety Act" must be amended to meet the Rule 24 of the "COLREG 1972". And also I wish to adhere to the importance of displaying the adequate vessel lights and shapes by every mariner for preventing marine accidents.

The Steering and Sailing Rules of International Regulations for Preventing Collisions at Sea now in use direct the best aid - action to avoid collision by the stand - on vessel. But these rules do not refer to the safety relative distance between two vessels when she should take such action. In this paper, the author analyzed the ship's collision avoiding actions from the viewpoint of ship motions and worked out mathematical formulas to calculate the relative distances necessary for taking action to avoid collision. Figuring out the values of maneuvering indices through experiments of 11 actual ships of small, medium, large and mammoth size, the author applied these values to the calculating formulas and calculated the minimum relative distances. The main results are as follows: 1. It was confIrmed that the stand - on vessel should keep the greatest relative distance for taking best aid - action to avoid collision when the cross angle of course was $90^{\circ}$ and near it(70-$90^{\circ}$ ). 2. When the cross angle of course was $90^{\circ}$ , the minimum relative distance of small vessel(GT: 160-650tons) was found to be more than about 6.8 times of her own length, and those of medium(GT : 2,300-3,500tons), large(GT : 22,OOO-62,OOOtons) and mammoth(GT : 91,000-139,000tons) vessels were found to be more than about 9.0 times, about 5.4 times and about 6.8 times of their own lengths. 3. It was confIrmed that collision danger was greater when crossing angle was obtuse than in an acute angle, therefore greater relative distance was to be kept by the stand - on vessel for taking best aid - action to avoid collision in the case of the obtuse angle. 4. In every vessels, in the case of $90^{\circ}$ cross angle of course the safety minimum relative distance was found to be more than about 9.0 times of their own lengths.

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 revolution, steering gear and forward reverse neutral gear controls. These three controls are made by position and speed control using DC motor, and microprocessor is used to communicate and control the engine speed This system can be controled and worked alone and we tested the system at sea and confirmed that the system works properly.
