"SEA-Arrow", developed by Kawasaki Shipbuilding Corporation, is an advanced new bow form for medium-speed ships such as LPG carriers. The bow end form of SEA-Arrow around the loaded draught is much sharper than that of conventional hull ships. With SEA-Arrow, bow waves are greatly reduced in loaded condition compared with conventional hull ships. Model tank test results show that SEA-Arrow can reduce the wave resistance to a half and the required main engine horsepower by 6-10%. On the other hand, the superiority of SEA-Arrow ships' propulsive performance in loaded condition cannot be verified in sea trial because actual ships' speed tests in sea trials are generally carried out in ballast condition except oil tankers. Therefore, the authors have analyzed, to confirm the high propulsive performance of SEA-Arrow ships, the voyage data of three SEA-Arrow ships and one conventional hull ship, which are sister ships of 59,200m3 LPG carriers. The results show that the propulsive performance of the SEA-Arrow ships is superior to that of the conventional hull ship and that its analyzed speed advantage agrees with the estimate from the model tank test results.
