To develop a sailing yacht successfully, systematic engineering information is required including technologies from various companies and know-how about sailing yacht. The engineering information about sailing yacht has a complex and extensive structure. Therefore, a robust and high-level of management system is needed to manage the information. In this paper, we design and propose Generic-YWBS (Generic-Yacht Work Breakdown Structure), a work breakdown structure for sailing yachts. The Generic-YWBS is aimed at constructing sailing yachts and contains contents about product- and process-oriented information of sailing yachts. In addition, the Generic-YWBS plays an important role in managing the engineering information as a basic schema of database and system architecture. The Generic-YWBS is derived from fundamental WBS design processes and various rules about sailing yachts, for example, ISAF (International Sailing Federation) equipment rule and IRC rating rule, and a generic structure concept is applied for flexibility. The Generic-YWBS is applicable for various purposes. We designed a detailed code system in order to apply the Generic-YWBS to contents management system. The series of activities are realized through a web-based RIA(Rich Internet Application) program. This program manages the YWBS structure in an XML schema, and the Generic-YWBS management application offers a customizing function to be adapted in the field.

Recently, the marine leisure industry has begun to make a mark on the growth engines of the Korean economy. Hence, various government research projects are in progress to catch up with the fundamental yacht technologies of advanced countries. Research on the integrated management technologies of sail yachts is carried out as a part of those projects. Work Breakdown Structure (WBS) is a basic architecture for robust and high-level management systems. In this paper, we suggest a product-oriented Yacht Work Breakdown Structure (YWBS). General WBS has a drawback in that it can only follow the targeted purpose, but YWBS allows for a generic WBS approach. This concept allows us to apply WBS to multi-purpose uses. The YWBS is used as an infrastructure in information management and for data relationships in sail yacht management systems. YWBS is designed and managed by a web application, and the system is implemented with a website as a user interface. This application has not only a design function, but also a data transfer function that is based on the Microsoft Silverlight platform, a kind of Rich Internet Application (RIA) technology. Using this application, YWBS designers can communicate with the management system without added tasks like as uploading and updating.

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.
