Zero torque
Post-swirl stator
The torque effect is a natural consequence of the propeller’s rotating action, which causes the water
stream to swirl, and creates a turning force on the scooter handle thus increasing diver’s fatigue
Inspired by jet engine constructions, Seacraft developed a post-swirl stator system, which
interacts with the propeller slipstream, changing its swirl to net thrust. This allows to completely
eliminate the torque effect, and simultaneously increase the propulsion system efficiency,
due to recovering usually lost water swirl rotation force.
