Boat, preferably speed-boat with reduced frictional resistance |
| 摘要 |
The boat body has a corrugated profile (4,41,42), its ridges (41) running in the direction of flow. The profile has a wave height (3) that corresponds to half the thickness of the boundary layer. The wavelength (30) of the profile is preferably four times bigger than the wave height.
