Are low noise levels important or do you have little immersion? If so counter-rotating propellers are the best solution, e.g. for a passenger ship.

Low noise
Counter-rotating propellers provide a new dimension to efficient and low-noise propulsion. By distributing the power over two (smaller) propellers, which will turn in opposite direction, higher efficiency is obtained when compared to a single propeller.

The advantages of counter-rotating propellers compared to a single open propeller:

Higher yields through minimal rotation loss
Lower blade load
Lower peripheral tip speed
Lower noise production
Little cavitation
Suitable for minimum immersion depth due to smaller propeller diameter
