This paper presents a new technique for reducing frictional drag using a super-water-repellent surface and air-injection
(called an SWR & A technique). Its effectiveness was examined by carrying out pressure-loss measurements with a tube of rectangular
cross section, along with resistance tests on a horizontal flat plate, a 7.2-m-long tanker model, and a 12-m-long high length-to-beam-ratio
model ship. These test results showed that the new technique can significantly reduce the models' frictional drag; for example,
the frictional resistance on the SWR surface was reduced by 80% at a speed of 4 m/s and 55% at 8 m/s.
