When backing a motor propelled lifeboat with the rudder amidships, which direction will the stern move if it has a right-hand propeller?

When backing a motor propelled lifeboat with the rudder amidships and a right-hand propeller, the stern will move to port. This behavior arises from the characteristics of a right-hand propeller, which is designed to rotate clockwise when viewed from astern.

When the vessel is moving in reverse, the thrust generated by a right-hand propeller pushes water down and to the starboard side. This action causes the stern of the boat to swing to port due to the lateral movement of water leaving the propeller.

Understanding this dynamic is crucial for effective maneuvering in various situations, such as docking or navigating in confined spaces. The propeller's rotation creates a directional force that influences the boat's motion, and recognizing this helps improve a lifeboat operator's handling skills.
