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.

The motor boat which is the principal equipment of marine leisure depends heavily an imported motor boats in Korea But because the demand of marine leisure and motor boat increases, it is necessary to develope a cheap and safe domestic-manufactured motor boat. However the development of motor but for marine leisure is not performed at all in Korea in this paper, we consider the concept design of public motor but for marine leisure. The present status and possession prediction of leisure boat are investigated at first. And the benchmarking of the overseas motor bout for marine leisure is performed. And next the required performance, the range of principal dimension and the needed equipment of the public motor boat are investigated based on the benchmarking results of the overseas motor boat. Finally, the example of hull form design for Public motor boat is showed

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.

The design trend of leisure boat has been developed through interrelation of maritime culture and ships. We studied the design trend of leisure boat of several countries with advanced maritime culture and proposed digital design process of electric boat exterior that could reflect sensibilities of Korean customers. The result could be useful to domestic small and medium-scale shipbuilders currently face global financial recession and new challenge to focus on development of eco-friendly leisure ships.

The propulsion type of a small boats mainly were divided that the In-board and In out-board position located engine. The boats of the In-board and In out-board engine individually were propelled by propeller and stern drive. In this paper, 39feet-class leisure boats with propulsion type of In-board and In.out-board engine were performed to compare the effect of resistance performance using model test. As a result, leisure boat with In out-board engine is ascertained the optimum boat affects the speed and fuel efficiency.

The cutting automation of boat's wooden pattern is strongly required to improve the productivity and quality of boats in leisure boat industry. This paper is concerned with the development of wooden pattern machining technology by the machining center. The leisure boat is designed with a 3 dimensional design s/w. The NC cutting data are generated in a CAM s/w and are verified using verification s/w. The cutting forces are monitored to analyse the cutting process. The surface characteristics of machined surface are investigated at various cutting conditions such as spindle speed, feed speed, the cutting direction of wood, and wood material.

This paper deals with the development of structural test facility for the strength assessment of marine leisure boat built from carbon fiber reinforced plastics (CFRP) materials. The structural test facility consists of test jig, load application and control system, and data acquisition system. Test jig, and load application and control system are designed to accommodate various size and short span to depth ratios of single skin, top-hat stiffened and sandwich constructions in plated structural format such as square and rectangular shapes. A lateral pressure load, typical and important applied load condition to the plates of the hull structure for marine leisure boat, is simulated by employing a number of hydraulic cylinders operated automatically and manually. To examine and operate the structural test facility, five carbon/epoxy based FRP square plates having the test section area of $1m^2$, which are part of CFRP marine leisure boat hull, are prepared and they are subjected to monotonically increasing lateral pressure loads. In the test preparation, considering the symmetry of the plates geometry, various strain gauges and linear variable displacement transformer are used in conjunction with data acquisition system utilizing LabVIEW. From the test observation, the responses of the CFRP hull structure of marine leisure boat are understood by obtaining load to deflection and strain to load curves.

Korea has been took the top ranking in the global shipbuilding industry in terms of new orders, order backlogs and the volume of vessels for several years. However, the domestic small- and medium-scale shipbuilders currently face imminent threat from China and new challenge to focus on development of high value-added ships. So far, the marine leisure industry of Korea has been showed weak global competitiveness and there were few attempts to design and develop leisure boats and yachts. We describe the digital design process of leisure boat exterior that could reflect user's sensibilities and feelings of entire forms of the products. This design process contains stepwise sensibility evaluation via web and provides designers with various and fast feedbacks about their design outputs in each design stage.

The 6m class high speed boat is developed with a durable hull and inflatable tube, which is called RIB(Rigid Inflatable Boat), for the purpose of marine leisure. In the stage of the conceptual design, its requirements to be optimized are determined based on the presented information of similar marine leisure RIBs. The 3-D graphical technique using Marine Rhino is utilized to optimize the compartment layout of RIB. The stability analysis is performed for the light and full load conditions with and without the inflatable tube. In addition, the sea keeping and hydrodynamic performance was tested using the proto-type ship in the sea condition. From the results of the computation and the sea trial test, it shows that the performance of the marine leisure RIB satisfies the speed, the convenience, and the stability requirements. This study provides the typical information of the design factors and the procedure to manufacture the marine leisure RIB.

In this study, the numerical simulation and basin model test have been performed to evaluate sea worthiness and resistance performance for a small pre-planning three type of leisure boats which are U, V, Y shapes of hull forms. As a well known commercial CFD code, Maxsurf, was applied for modeling hull forms used as the solver of motion analysis. Also the model resistance test was carried out to estimate the effective power of boat in the basin tank. Numerical simulation and model test results show that Y-shaped hull is better than the other types in terms of heave and pitch motion, having a key effect on a boat sea worthiness. But V-type hull is more efficiency than others cases in resistance performance.
