The demand for sailing yacht is increasing in consonance the improvement of people's live. These yachts can be dually propelled by wind and by diesel engine power. A singing (humming, whistling) phenomenon induced on the propeller was discovered on a 55-foot catamaran sailing yacht. As a result, an increase in the structural vibration of the stern tube room and propulsion system with abnormal noise was detected due to this flow. In this study, the cause of the phenomenon is investigated and its possible countermeasures proposed.

The space of leisure boats & yachts is formed by interior design elements and shapes are formed by combination of those elements. By means of configuration of the design elements, space is made in a ship and patterns in an inside space are made through production. These space can be categorized as (1) cabin(common cabin, staterooms, one-cabin), (2) salon, (3) galleys & dinette, (4) heads(showers, toilets, bidets, sinks), (5) cockpit, (6) wheelhouses, navigation stations, (7) fore peaks, (8) engine room, (9) deck etc. Interior materials are classified into (1) walls(bulkheads & lining wall), (2) floors(sole), (3) ceilings(overheads), (4) doors & windows, (5) furniture, (6) lightings and (7) Hardware & decoration in large, medium and small sizes, which constitute interior design elements of a leisure boat & yacht. The materials used in leisure boats & yachts have properties of lightweight, noise and vibration resistance, fire & flame retardant, stability, strengths, lifespan, appearance and special operation in construction.
