Recently, the demand for marine leisure industry is rapidly increasing due to the five-day work week and the per capita income approaching US $ 30,000. In particular, the Republic of Korea is surrounded by the sea on three sides and is composed of 3,150 islands and coastline. As shipbuilding infrastructure is abundant and the government is expected to actively support policies as a new growth engine, leisure boat furniture industry is expected to grow rapidly along with leisure boat manufacturing. Therefore, in this paper, after understanding the leisure boat (yacht) and analyzing the requirements of yacht furniture, we proposed a beautiful yacht furniture design that is lightweight, durable and safe using a 120-foot super yacht that can best show the characteristics of yacht furniture using wood bending technology and color variation of woods.

Korea has been took the top ranking in the global shipbuilding industry in terms of new orders, order backlogs and the volume of vessels for several years. However, the domestic small- and medium-scale shipbuilders currently face imminent threat from China and new challenge to focus on development of high value-added ships. So far, the marine leisure industry of Korea has been showed weak global competitiveness and there were few attempts to design and develop leisure boats and yachts. We describe the digital design process of leisure boat exterior that could reflect user's sensibilities and feelings of entire forms of the products. This design process contains stepwise sensibility evaluation via web and provides designers with various and fast feedbacks about their design outputs in each design stage.

The objective of the present study is to design a hull form of a 9.77 ton class trimaran for use as a Pleasure boat around the bay of Gyounggy. The boat will be made of fiber reinforced plastics and equipped with a 650 hp diesel engine with a conventional water jet propulsion system and the maximum speed be 25 knots after fully loaded. In the present study, the optimal configuration such as relative location of outriggers of the 9.77 ton class trimaran is selected and the resistance characteristics are carefully studied through a series of model tests. The general arrangement of the boat are also considered in the final decision of the hull form.

해상교통관제(VTS, Vessel Traffic Service) 구역에서는 선박의 항해뿐만 아니라 준설, 급유, 수상레저, 어로, 군사훈련, 모래 채취 등 다양한 해양 활동이 동시에 이뤄지고 있다. 이들 활동들은 제한된 공간에서 경쟁적으로 이뤄지기에 시 공간적 충돌을 수반하게 된다. 최근 VTS는 '해상교통서비스' 라는 본연의 역할과 더불어 다양한 해양 활동들이 조화롭게 이뤄지도록 조율하는 영역까지로 확대되고 있다. 이렇듯 발전하는 VTS의 역할에 발맞춰 관제 구역에도 해양공간계획(MSP, Marine Spatial Planning) 개념을 도입하여 체계적인 접근이 필요하다. 본 연구에서는 해양공간계획을 도입한 타 국 사례를 소개하고 그 도입 필요성에 대해 제안 하고자 한다.

최근 해양 분야에서는 레저보트, 윈드서핑, 낚시 해상관광 등 해상에서 활동이 증가됨에 따라 선박의 안전을 비롯하여 해상 활동을 위한 다양한 정보 제공 요구가 점차 늘어가고 있다. 해상활동을 위한 정보제공은 사용자의 위치를 기반으로 사용자에게 적합한 정보의 제공이 필요하다. 특히, 전자해도 상에 사용자의 위치 또는 사용자가 지정한 위치를 기반으로 정보를 제공하는 위치 기반 정보 서비스의 제공 요구가 늘어나고 있다. 본 논문에서는 사용자의 위치 또는 사용자가 설정한 위치를 중심으로 전자해도 상에 정보를 표시하여 제공하는 정보시스템 모델을 제시한다. 본 논문에서 제시하는 시스템은 사용자 디바이스로부터 획득한 위치정보 또는 사용자가 전자해도 상에 지정한 위치를 바탕으로 항로표지 정보, 일출, 일몰, 간조, 만조, 날씨 등을 표시하여 제공한다.

풍랑특보는 우리나라 부근을 항행하는 선박 및 해상 업무 종사자에게 큰 영향을 미친다. 이 연구에서는 최근 11년(2010-2020년) 동안 기상청에서 발표한 서해·남해·동해의 앞바다 및 먼바다, 제주도 앞바다의 풍랑특보와 주요 해양기상부이의 관측자료를 비교·분석하여 풍랑특보의 적절성을 평가하였다. 각 해역에 대한 풍랑특보와 해양기상부이 관측자료를 일별, 월별, 연별로 통계를 내어 연평균, 월평균, 계절별로 비교한 결과, 풍랑특보의 적중률이 전 해역에 걸쳐 매우 낮은 것으로 분석되었다. 해상에서의 풍랑특보가 어선의 어업활동, 여객선 운항 및 관광, 해상 레저활동 등에 미치는 영향을 고려할 때 해양기상 예·특보의 정확성을 개선할 필요가 있음을 확인하였다.

The ship's seakeeping performance in the pitching and roll motion was felt tired. These gives structural loads to loaded with cargo and hull facilities. Be to improve, small catamaran power yacht designed a data for ship research and ship's hull form to be decided. In this study, based on domestic release for coastal marine environment in the interpretation criteria were chosen based on the exercise performance. The seakeeping performance of marine leisure catamaran was based on voyage speed. The seakeeping performance estimates based on the encounter angle, the wave of the encounter frequency response amplitude ratio for exercise was assessed in the high performance area.

ISO 12215-5 standard describes allowable stress design specifications of monohull small boat with a length of hull between 2.5 m and 24 m constructed from fiber reinforced plastics, aluminium or steel alloys, glued wood or other suitable boat building material. If small boat hull is under 2.5m in overall length or nonstandard material is used as boat building material, structural reliability of small boat hull is assured by drop test specification, but not by structural design specification in accordance with ISO 12215-5. Drop test specification of boat hull can be applied to manufactured product. But it is difficult and complicated to apply drop test specification to structural design of boat hull. In this study, we present structural design method of polyethylene boat hull on the basis of longitudinal bending strength test specification.

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.

As the demand of sea leisure increases recently, interest is converged sea safety and offer of quick and systematic information according to weather environment that change rapidly. Use of Electronic Navigational Chart(ENC) in the sea in offer of geography information through Mobile terminal was gone to level that run in PDA environment in domestic by bulky good physician data information and complicated processing way of island in the sea expression in sea, and is loaded in obligatory sailing equipment of ship yet and is used. In this paper, we develop server system that take charge index for offer of quick information through Restrictive resource management and Caching Technique, image conversion and database construction and fast search to service various marine leisure informations of Weather Data and so on and image information of ENC in the sea to Mobile portable phone terminal efficiently.
