This paper reports the hull form development and resistance performance of a 5-ton-class catamaran-type coastal fishing boat. The weight estimation and preliminary design were basically extracted from existing coastal fishing vessels. In addition, the resistance performance was investigated using a model test in a high-speed circulating water channel and was analyzed in comparison to an existing catamaran fishing vessel. As a result, the modified hull achieved an approximately 30% reduction in resistance compared to the previous hull. The stability or boarding sensitivity of the modified hull form was more stable or comfortable than the original hull form based on a trim and sinkage comparison between the two boats.

Resistance performance of small size fishing vessel is experimentally investigated to find out the effect of fore-body shape and trim for the better hull form development. The tests are performed for four different cases in the high speed circulating water channel(CWC). Wave patterns are observed together to investigate the relation between the resistance performance and the wave characteristics.

This paper presents a mathematical method that represents efficiently high-speed coastal fishing vessel. That is, it represents the numerical hull by using irrational function and hull form characteristic curves, which define a hull form under design conditions. Then it suggests a process that hull form characteristic curves are represented with NURBS and hull form is varied.

Resistance performance of 6.67 G/T class fishing vessel is experimentally investigated in low and middle speed ranges to find out the effect of a new chine. The tests are performed for four different cases in the circulating water channel(CWC). Wave patterns are observed together to make clear the relation between the resistance performance and the wave characteristics. The results show that the new chine can be one of the effective device to reduce the resistance.

This study proposes the improvement of maritime traffic management for domestic ships and fishing vessels by introducing the e-navigation environment. This study discusses the development of present Vessel Traffic service (VTS) in a systematic aspect and a fuctional aspect. The concept and architecture of e-navigation operation system based on the General Information Center on Maritime Safety and Security (GICOMS) are proposed as a solution for the improvement of maritime traffic management in Korean coastal waters. Especially, means of data exchange between ships and ship-shore based on the Maritime Cloud and regional e-Data Center are discussed. This study will help to the implementation of the Korean e-navigation project which focuses on the safety of small ships and fishing vessels. In the future, it is needed to study for the development and operation of accident prevention system under the e-navigation environment.

최근 우리나라는 연근해 어업에 대한 환경변화가 심화되면서 어로작업의 생력화 및 지역특성에 알맞은 어구어법개발이 필요시 되고 있는데 제주도의 경우 주변국가와의 어업협정 이후 어장축소 등으로 말미암아 종래의 어선어업이 위축되면서 따라 연안 유용수산자원 생산성 향상을 도모하여 어민소득증대에 기여할 새로운 어구어법 개발이 시급히 요구되고 있다. 학공치 표층예망어구는 장래 이러한 문제를 해결 할 수 있는 연안어업의 하나이다. (중략)

국제해사기구(IMO)에서는 인적과실의 예방과 항해사의 업무부담 경감을 위하여 e-navigation의 도입을 추진하고 있고 전략이행계획에 따라 2019년까지 e-navigation의 구현을 위한 관련 지침의 개발과 협약규정 제 개정작업이 활발히 진행 예정이다. 해양사고에 취약한 소형선박이나 어선에 e-navigation적용위해서는 사고예방에 관한 시스템의 개발과 구축이 필요하다. 본 연구에서는 IMO의 e-navigation 솔루션과 현재 정부에서 추진중인 한국형 e-navigation 구축사업 내용을 바탕으로 향상된 개념의 소형선박의 선박충돌예방지원시스템을 연구하여 제시하였다. 이 연구가 e-navigation이 실질적인 해양사고 예방에 효율적으로 활용되는데 정책적인 측면과 실무적인 측면에서 기여할 수 있다고 보며, 특히 연안선박과 소형어선의 안전증진에 기여할 수 있기를 기대한다.
