When backing a lifeboat with rudder amidships (with right-handed propellers), the boat will back to which side?

Backing a lifeboat relies on the way the propellers push water when you move in reverse and how that interacts with the rudder. With right-handed props, which rotate clockwise when viewed from the stern, reversing thrust creates a clockwise swirl that tends to push the stern toward the port side. When the rudder is amidships, it doesn’t provide a strong steering moment in reverse, so that propeller-induced yaw dominates. The result is the boat backs toward the port side.
