The purpose of this study is studying the relationship among experience choice, experience effect and experience satisfaction of marine leisure sports for the vitalization of marine leisure tourism. After preparing a questionnaire, investigation and analysis were done by visiting Boryeong area. The result of the study is as following. First, it was found that the major cause of choice in marine leisure sports has positive impact on choice satisfaction. Second, it was found that the major cause of choice has positive impact on experience effect. Third, it was found that the choice satisfaction in marine leisure sports has positive impact on experience effect. Fourth, it wa s found that the marine leisure sports visitors like motor boat, banana boat and yacht experience. Fifth, it is suggested that an equipment rental desk, safety facilities and marine leisure experience facility included in a marine leisure experience center to be built.

The sense of touch by natural wind is one of the most common feels that every person experiences in daily life. However, it has been rarely studied how natural wind can be reproduced in a VR environment and whether the multisensory contents equipped with artificial winds do improve human emotion or not. To address these issues, we first propose a wind reproduction VR system guided by video and wind capture data and also study the effect of the system on positive affect. We collected wind direction and speed data together with a 360-degree video on a yacht. These pieces of data were used to produce a multisensory VR environment by our wind reproduction VR system. 19 college students participated in the experiments, where the Korean version of Positive and Negative Affect Schedule (K-PANAS) was introduced to measure their emotions. Through the K-PANAS, we found that 'inspired' and 'active' emotions increase significantly after experiencing the yacht VR contents with artificial wind. Our experimental results also show that another emotion, 'interested', is most notably affected depending on the presence of the wind. The presented system can be effectively used in various VR applications such as interactive media and experiential contents.

The chine of high speed vessels does not only play a role in changing position when planing but also helps balancing the hull. It also has a great influence on resistance performance. However, designing a chine requires a lot of experience because it is influenced by various factors such as displacement, transom shape, draft and width. Such a design is not based on an empirical formula, but the purpose of this study is to provide basic guidelines regarding the shape of chine through calculation. This design was developed using Yacht-one, a commercial design program, and analysis was performed using Star-CCM+, also a commercial analysis program. Analysis of the hull selected in this study was carried out by Dynamic Fluid Body Interaction (DFBI) method. Analysis of the chine was carried out at chine angles of 15, 16, 17, and 19degrees, at a speed of 30knots. The result indicated that the highest trim occurred at 16 degrees among the four chine angles considered, and the highest heave occurred at 15degree. In terms of resistance performance, minimum resistance was observed at 16 degrees. Consequently, for minimum ship resistance, it is necessary to complete calculations in accordance with the chine angles, ${\pm}2$ degrees from the initial chine angle, which should be carried out a the design stage.

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.
