Many countries foster the tour and leisure industries as a national strategic industry of the 21st century. The tour and leisure industry is expected to be reorganized from the land-based industry to the ocean-based industry as the GNP in a nation is over USD $20,000{\sim}30,000$ dollars. In Korea, since we adopt a five-day week, the total working hours for a week is shortened. As the result, leisure activities in family, such as experience tour, ecological tour, travel, and overnight tour, are expected to be increased. Leisure and sports tours, which link the tour and sports to rafting, hang gliding, and marine leisure, have been also increased over 21.6%. A number of small and big islands near Ho-Nam coastal areas play an important role as natural breakwater. Thus, the ports in Ho-Nam area is safely protected from physical effects by ocean waves and is maintained without constructing a breakwater. In this paper, we analyses the required conditions as the marine leisure base in the southwest sea area which has the natural advantages for marine leisure. We also discuss how to activate the yacht business on Ho-Nam coast area. And then we analyse the present situations and obstacles of a domestic marine leisure. We also suggest the plan to build up echo-marine leisure infrastructure for industrial growth of marine leisure in Ho-Nam area.

Recently, our country is to be diversification a leisure activity and tourism form by income level rise and traffic circumstance improvement. But Basic facilities expropriated these leisure activities have built an insufficient condition. Also, Building a facility, Introduced tools and materials import the whole quantity. Therefore, In this paper, it builds a tension mooring unit to use EPDM and Kevlar R29 and it develops a domestic marine circumstance through reliability based on robust design. It contributes to marine leisure culture activation and industry development.

Since 2000, S. Korea is building yachts through government supported localization, cooperation between industry and educational organizations, or partnerships with foreign firms but the yacht building has yet only accomplished trial manufactured ships and one-time production. Because of a lack of mass production, the industry assesses the domestic technical skills to an average 50~60% of developed countries and its market share is less than 1% in the world. In addition, domestic marine equipment is heavily depending on imports and the industry is experiencing shortage of technology and experts, small-sized companies, insufficient industry and educational organizations' cooperation networks, inadequate legislation and policies, deficient domestic market vitalization, and scarce international information. Thus, this study focuses on the alternative plans to strengthen competitiveness and to cope with problems in the southeast marine leisure equipment industry.

The leisure boat industry has the potential to become a high-value-added industry in the future. Recently, a study on Korean high-speed leisure boats for fishing was conducted. This study suggests a product configuration model-based shipbuilding cost estimation method for determining the type of leisure boat suitable for mass production, as part of a research for productivity improvement. The suggested estimation method based on the analysis of the leisure boat process and generic YWBS can calculate quantitative and concrete data. By using this method, the cost of building the catamaran-type design ship can be reduced by 17 times, compared to that of the monohull-type mother ship. This implies that the final design of the Korean high-speed leisure boat for fishing will have a competitive price at the actual production stage.

The aim of this study was to experimentally investigate the hydrodynamic performance of a hemispheric wave energy converter (WEC) and its wave power takeoff. The WEC is a heaving body-type point absorber with a hydraulic-pump power take-off (PTO) system. The hydraulic PTO system consists of a hydraulic cylinder, hydraulic motor, and generator, with consideration given to the hydraulic pressure and flow rate. Two body model shapes, including the original hemisphere and a bottom-chopped hemisphere, were considered. The heave RAOs of the two models were evaluated for various body drafts. The effects of the hydraulic PTO system on the RAOs were also investigated.

A leisure ship has a stand-alone type power system, and a generator is in use on this condition. But the generator cannot be operated in condition of leisure activity, ocean measurement and etc, because of environment and noise. Recently, renewable energy system is connected with power system of the leisure-ship for saving energy. The renewable energy system can not supply the stable power to leisure-ship because power generation changes according to weather condition. And most of the leisure ship is operated without methodical power management system. This study's purpose is to develop SPMS(Smart Power Management System) algorithm using the renewable energy (photovoltaic, wind power and etc.). The proposed algorithm is able to supply stable the power according to operation mode. Furthermore, the SPMS manages electric load (sailing and communication equipment, TV, fan, etc.) and reduces operating times of the generator. In this paper, the proposed algorithm is realized and executed by using LabVIEW. As a result, the hour for operating the generator is minimized.

As leisure boats become large-scaled and high value-added, their design requirements gradually get more complicated and accordingly their manufacturing processes get more complicated than those of existing ones. Leisure boat builders overseas make efforts to overcome this circumstance by establishing a 3-D model-based design system which is based on the concept of PLM. On the other hand, Korean shipbuilders still remain in the development process of traditional leisure boats which are mainly based on 2-D drawings. There have been some efforts made to have the 3-D model-based design system; however, they belong to a very early stage. This study carried out initial research to apply DMU technology to the development process of leisure boats. It established the design process based on a DMU model and proved its usefulness through a case study on the design of 40-ft class aluminum leisure boats.

The base of leisure air activities are consistently expanding and its demand is expected to increase attributed to GDP growth and people's interest in its activity. Utilizing Visual Flight Rule, light sport aircrafts and ultra-light aircrafts are not under the effect of air traffic control center, which resulted in passenger injury due to emergency landing for adverse weather conditions and technical issues after pulling into mountain area, ocean and even urban area. Such events encouraged safety consciousness toward leisure aircraft activities and developing a measure to prevent a recurrence of the accident. This research focuses on suggesting compositive system for preventive safety management system by providing user based Flight information service and operating effective system, necessary for leisure aircraft activities.
