The Side by Side Propeller

With the Side by Side Propeller (SbS), the drive power is distributed over 2 propellers. This reduces the necessary propeller diameter to around 70% of a single propeller, with the same ratio of drive power to thrust. This reduces the necessary draft of a ship. The counter-rotating propellers bring a gain in efficiency through a partial recovery of the swirl component of the propeller water.

The SbS is a patented invention by Siegfried Lais.
The patent is owned by
