본 논문에서는 7m급 고속 Stepped Hull 구난정의 선형 개발을 위한 초기 단계로서, 스텝(Step)의 개수에 따른 최소저항 구난정 개발을 위해 동일 단변형상과 배수량을 갖는 스텝(Step)이 없는 (Non-Step)선형과 1스텝(Single-Step)선형 및 2스텝(Twin-Step) 선형을 대상으로 먼저 회류수조 선형시험 결과를 비교 분석하였고, 회류수조 유속한계에 따른 고속영역에서의 스텝(Step)개수에 따른 저항특성 비교는 상용프로그램인 Fluent를 이용하여 해석 하였다.

Hybrid propulsion system for fishing boat consists of diesel generator, battery charger and battery as propulsion power source. In this system, battery charging system is very important for propulsion safety. The battery charging system is operated with according to the load of generator. The most important design conditions of hybrid system are a characteristic of ship, charging efficiency, low-speed sailing condition with battery. This paper is presented the simulation result with design condition.
