Resistance and Propulsion of Inland Water Cargo Vessel

하천화물운반선(河川貨物運搬船)의 선체저항(船體抵抗)과 추진(推進)에 대(對)하여

In recent days, many manufacturing factories have been established and operated along riversides or on sea coasts. In consequence thereof, modern inland vessels with their small draught but large carrying capacity have been developed to operate as a single unit or in convoy with a barge. Knowledge in the behaviour of inland cargo vessels in shallow water exists presumably in U.S.A., U.S.S.R. and West Germany Literature available on this subject is quite limited. Model tests were carried out, both in calm water and in waves to obtain hull lines, which not only improve the seaworthiness of inland vessels but also permit to run in convey with other vessels on inland waterways. The results, which to some extent have also been tested in full scale, are entirely satisfactory. This paper discribes the resistance of some newly developed inland water cargo vessels.
