The South Korean marine industry is emerging as a significant market, driven by the growing popularity of various water leisure activities, including sailing. This trend suggests a rising demand for sailing yachts. Consequently, since 2022, the design and development of a 28ft sailing yacht have been ongoing, supported by the government and the Ministry of Oceans and Fisheries, to promote yachting culture in South Korea. The Velocity Prediction Program (VPP) analysis was conducted using WinDesign during the preliminary design stage to evaluate performance and determine design parameters. The hydrodynamic model used for this vessel is based on regression methods developed from years of experience in naval architecture and yacht research at the Wolfson Unit, providing reliable estimates for most modern yachts. However, owing to the lack of specific hydrodynamic data from towing tank tests or CFD numerical analysis, verification of the hydrodynamic model has faced some challenges. Additionally, an incomplete weight estimate resulted in variable VCG values, potentially affecting stability and overall performance. The optimal boat speed for this vessel was determined at true wind speeds (TWS) of 4, 8, 12, 16, and 20 knots, using both the jib (up to 120° TWA) and the spinnaker (from 80° TWA). The optimized speed of the yacht was found to be comparable to that of international similar-class yachts.

우리나라 첫 연안VTS인 진도 연안VTS의 운영 성과를 분석하고, 운영 사례를 조사하여 연안VTS기능에 관하여 실증적으로 분석하였다. 연안VTS는 관제구역이 넓어 해상교통 특색이 장소마다 상이하며, 집중 관제를 필요로 하는 곳이 많았고, 통항선박 중어선과 같은 비관제 대상 선박이 다수를 차지하여 이들의 관제가 중요한 것으로 조사되었다. 그리고 선박 운항자의 집중도가 항내보다는 떨어지므로 인적과실에 의한 사고 개연성이 높은 것으로 분석되었다. 연안VTS는 항만VTS와 같이 정보제공, 항행지원, 교통관리의 역할을 주로 하고 있지만, 수색구조 지원, 해상 보안, 해상치안 업무, 해양오염 대응, 비관제 대상 선박 업무 및 수상레저 안전관리 등의 기능을 강화되는 것으로 나타났다.

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.

Securing safety in the maritime danger zone around the launch site before a launch is a fundamental requirement. If maritime safety is not ensured, the launch is halted or postponed. However, challenges have arisen in the process of securing public safety at sea due to factors such as the increasing population engaged in water leisure activities. These challenges include unauthorized entry of vessels into controlled areas, unauthorized access by water leisure activity participants, and non-compliance with regulations. In this paper, we employed the Delphi/Analytic Hierarchy Process to survey 22 experts, including professionals in launch vehicle development and launch site operation, to identify 10 factors posing threats to maritime public safety. Additionally, we identified five issues that need improvement for ensuring maritime safety. This study verified the consistency of expert opinions and conducted an analysis of importance and prioritization, objectively confirming the necessity for amendments to relevant laws or the enactment of new laws concerning the establishment and control of danger zones around launch sites.

This study aims to prepare countermeasures to prevent and minimize drowning accident in inland waters by examining the current status of inland water safety management in Korea and diagnosing the defects. The defects in current inland water safety management is analyzed in four aspects. First is the legal defect that includes the absence of legislation that directs the inland water safety management. Second is the instructional defect such as the absence of educational program for prevention of inland water accidents and lack of professional water rescue experts. Third is cooperation defect such as dispersed reporting system and lack of private-public partnership in accident response. Fourth is the defect of emergency response ability, professionalism and accident response skills due to the dispersion and overlaps of safety management systems. In order to improve these defects, this study finds the countermeasures based on the survey of water sports professions and users and its analysis as follows: legislation of '(tentatively named) special act for water safety management in inland waters' is suggested in the legal aspects. A development of inland waters safety education program and training of water accident experts are suggested in the instructional aspects. Integrated operational system for water accident management, activation of safety network and re-establishment of private-public partnership are suggested in the cooperation aspects. Systematic and efficient inland water safety management plans such as enhancement of accident response skills and expertise and integrated inland water safety management with fire department-centered system were suggested in the aspects of emergency response ability.
