광폭 고속 활주선 선형개발에 관한 연구 A Study on Hull Form Development for a Wide Beam High Speed Planing Boat
pp.1065-1070
In this study, a high speed planing boat with 7.2 meters in length is developed as the beam larger about 10% by comparing with the general planing boat. The design speed of a boat is 30 knots (about 15.4 m/s) by using 150 hp outboard engine and the main material is FRP. The resistance performance related to the free running attitude as trim and sinkage is discussed and the wave patterns are observed to clear the relationship between the performance and wave characteristics by model test. The turning circle is estimated by Lewandowski´s equation. The results show that not only the wave pattern but also the free running attitude of the boat have the strong influence on a resistance performance. The boat needs smaller engine power and has more stable running attitude because of large sinkage and small variation of trim due to the large area for the lift force and light weight.
