Recently, research and development of high-value leisure vessels has been carried out in Korea to revitalize the marine leisure industry and tap into the global maritime leisure market. FRP composite materials, which have excellent physical properties and are available for the manufacture of light hulls, are used widely. One of the most important design technologies is to secure structural safety of leisure vessels made from FRP composite materials. In this study, the structural strength was assessed for the design of an 8-meter high-speed planing leisure boat made from FRP composite materials. The design loads to verify the structural safety were calculated according to the rules for the classification of high speed light craft (KR, 2015), and structural analysis was conducted using a finite element model composed of an isotropic shell element, which has equivalent bending rigidity with the FRP sandwich panel. The analysis results were compared with the results of the strength test for fabricated specimens, and all internal structural components are sufficiently satisfied with the structural strength.

'KS V 0054–단정용어' 는 '스포츠 및 오락용 단정' 의 용어에 대하여 규정하고 있다. '스포츠 및 오락용 단정'은 "플레저 보트" 라고 부르기도 한다. 특히, 단정(短_짧을 단, 艇_거룻배 정)은 소형선의 총칭으로 현재 국내에서는 소형 선박, 레저 보트, 플레저 보트, 레저 선박, 수상레저기구, 동력수상레저기구 등 용도 및 관계 법령에 따라 달리 정의하고 있다. 이에 일본식, 한자식 용어와 외래어가 혼용되어 사용되고 있는 플레저 보트(선체, 의장품, 범장 등)의 용어 표준화 방안을 제시 하고 또한 'KS V 0054–단정용어' 의 개정 방안을 제시 하고자 한다.

Characteristics of restoring force for the wind-powered leisure boat was investigated using mathematical formulation and commercial computational method such as the ANSYS Workbench CFX-Mesh. The objective is to find the restoring moment and heel moment while boat is sailing in windy power. Conditions for angle of attack were given from $5^{\circ}$ to $90^{\circ}$. It is known that side force is larger in terms of angle of attack is higher, however critical angle is suggested to limit before over of $60^{\circ}$ for safe navigation for boat in wind. Natural results are found that stronger heel moment is observed when sail is used than no sail, and higher angle of attack is induced stronger heel moment.

연안 어족자원의 감소, 노령화로 치닫는 어촌인구구조 그리고 어선감척사업 등으로 인하여 어항 또는 항만 등 인프라의 활용도가 저하되고 있어 기능재정비가 요구된다. 반면 해양레저활동에 대한 수요는 급증하고 있으나, 레저선박을 위한 기반시설 마련에는 막대한 재원이 소요되기에 사업화에 어려움이 잇다. 이 연구에서는 해양레저활동 기반시설로서 어항 또는 항만을 어떻게 활용하는 것이 바람직한지 그리고 레저를 즐기는 집단과 지역주민 사이의 갈등해소에 대한 방안을 모색하고자 한다.

This study analyzes the operating conditions of domestic marinas in response to changes in marine leisure trends and demand for recreational boats, and suggests ways to improve services according to the types and functions of marinas. In order to popularize marine leisure and to foster coastal and marine tourism industry, the 'Act on the Development, Management, etc. of Marinas' was enacted in 2010 and 'The 1st Marina Basic Plan' was established, and more than 34 marinas are operated nationwide. In order for domestic marinas to be used as an infrastructure for marine leisure activities, measures for enhancing service functions should be prepared in accordance with the size and characteristics of marinas. It is also necessary to improve facilities for marine leisure management and tourist convenience.

In this study, a conceptual study was performed for the leisure boat simulator used for navigation training. The aim of this work was to secure the basic operational capability of a leisure boat as a simulated driving device for a general novice operator. A leisure boat simulator was designed to support a user more efficiently regarding navigation proficiency and safety training, as well as to minimize the limitation of place and time and it conveniently and cheaply. A cockpit for navigation status display and operational input, 3D visualization graphic device, and parallel display device were designed to give the trainee a maximum sense of reality by applying a motion platform with six degree of freedom, in which disturbance movement such waves, winds, and tide were simulated for the operator. Leisure boat simulator training scenario was developed by analysis of water-related leisure activities act and sea traffic safety act.

국제표준규격(ISO 12215-5) 및 국내 플레저보트 검사지침의 개정에 따라 길이 6미터 미만의 플레저보트의 낙하시험에 의한 강도시험기준을 적용 가능하게 되었다. 하지만 현재 낙하시험은 자유낙하 시 내력 및 외력에 의한 선체 내부의 찌그러짐, 크랙, 박리, 파손 등을 육안으로 검사하는 방법으로 시험결과의 정량적인 판단이 이루어지지 않고 있다. 따라서 본 연구에서는 레저선박의 낙하시험을 위한 시스템 및 운용프로그램을 개발하여 플레저보트의 구조안전성의 정량적 평가가 가능한 시스템을 개발하고 다단 롤포밍 기법을 적용한 5m급 알루미늄레저보트에 적용하여 시스템의 성능을 검증하였다.
