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.

Although a yacht sails operate with large displacement due to very thin thickness, many studies for flow around yacht sails have not considered the sail deformation. The sail deformation not only caused a change in the center of effect(CE) on the sail but also a change in the thrust of the sail. The change of the CE and thrust affects the center of lateral resistance(CLR) and side forces of the hull, and the balance of the yacht. These changes affect the motion of the yacht which changes the velocity of the yacht. Thus, when analyzing the flow around yacht sails, the sail deformation should be considered. In the present study, fluid-structure-interaction(FSI) analysis of a two dimensional section of yacht sails was performed to consider the effects of sail deformation on the lift and drag performance. FSI and moving mesh methods were studied. Computational methods were verified using benchmark test cases such as the flow around horizontal and vertical cantilever beams. Shape deformation, pressure distribution, lift forces and separation flow were compared for both rigid and deformable sail.

A model test was carried out, in order to verify the hydrodynamic performances of public 30 feet class sailing yacht. In the initial design stage, the performances and the running attitude of sail yacht including the hull form and sail plan, appendages were estimated by VPP, from which made the representative test conditions. A new experiment system such as captive model device was composed because the running attitude could be changed by wind conditions. The test results show that the minimum resistance is generated in the heeling 20 degree. which was expected in the initial design stage. It is thought to be the useful informations that the keel has an effects on hydrodynamic forces and resistance differences between the upwind and the downwind condition. Also this paper is associated with the state-of-the-art of calculating sailing yacht performance as this is performed in velocity Prediction program (VPP) The VPP results shows a typical shape of a sailing yacht and the designed yacht has the best performance at 120 degree angle of true wind with 20 knots.

Leisure activities alter overland tourism into marine tourism according to a rise in national income. It is expected that the leisure boat with period of introduction in marine tourism will be developed rapidly. It needs to unite with marine technology, optimized layout design, interior design and so on in order to build a yacht of high quality. Because optimized layout design and interior design technique increase the added value of the yacht, it needs to be convergence technology between Ergonomics, Sensibility Ergonomics, and design technique. In this study, we analyzed traffic line of crews in a sailing yacht and assessed working posture using OWAS, RULA and REBA tools. Also we suggested tips of Ergonomic design in the sailing yacht.

Recently, according to the increase of income and development of quality of life, the leisure industry has been developed. In particular, the interest of design and manufacture technology of leisure yacht has significantly increased. However, domestic market of leisure ships is currently in its initiating stage. So research and development for structural strength of leisure yacht need to be investigated. In this study, lug of yacht's mast which is known for a critical damage region is explicitly considered. This paper deals with the estimation of stress concentration factors (SCFs) for lug of yacht's mast depending on dimensions of lug using hot spot stress. Also, SCF formulae is suggested using parametric study.

본 논문에서는 해양레저분야에서의 현재 복합재 적용 현황과 33피트급 아메리카스컵 훈련용 세일링 요트 개발에 대해 기술한다. 항공분야와 달리 해양레저 분야에서의 복합재료는 최근에서야 적용 및 사용이 되기 시작했다. 다양한 해양레저 구조물 중에서도 특히, 아메리카스컵 세일링 경주 요트는 빠른 속도를 내야 하기 때문에 경량화 및 높은 기계적 성능이 요구되고 이에 따라 경주용 요트를 건조함에 있어 탄소섬유의 사용은 필수적이다. 탄소섬유강화 플라스틱 경주용 요트 제작 과정을 정립하기 위해 탄소 돛대와 탄소 요트 선체에 대한 최적화 설계와 생산 공법에 대해 논의되었다. 최종적으로 이렇게 제작된 탄소섬유강화복합재 세일링 요트는 운항시험을 통해 경주용 요트로써의 높은 성능을 보여주었다.
