Sažetak
The SWATH technology improves the seekeeping characteristics of ships due to the use of underwater hulls. To reduce the energetic needs of such vehicles and pollution the special nseparated hull shapes can be used. Wind tunnel tests revealed the absence of separation on proposed bodies of revolution at large Reynolds number range. These facts open wide prospects for the use of unseparated shapes in order to improve the commercial effectiveness of vehicles. For example, for a SWATH yacht the weight-to-drag ratio can be estimated approximately 165 and is 3 times higher than the estimation of lift-to-drag ratio for Solar Impulse 2 plane. Thus, such yacht can use electrical engines only and reduce the pollution. It is also possible to use solar sells to charge the batteries for the same yacht.
