Answer :

Transverse thrust, also known as 'propeller walk' or 'paddle wheel effect,' is a lateral force exerted by a rotating propeller in water, which causes a boat to yaw or turn. This effect is influenced by several factors which we will examine to identify the correct option from the choices provided:

A) Propeller RPM: The transverse thrust effect is directly dependent on the speed at which the propeller rotates. Higher revolutions per minute (RPM) increase the rotational force acting on the water, thereby enhancing the lateral thrust or side force. This makes 'Propeller RPM' a key factor influencing transverse thrust.

B) Rudder area: The rudder area primarily affects the steering effectiveness of the vessel but does not directly impact the transverse thrust generated by the propeller.

C) Windage: Windage refers to the wind's effect on a vessel's exposed surfaces, causing drift, but it is not related to the propeller's transverse thrust effect.

D) Bow design: The shape of the bow can affect how a boat cuts through the water but does not directly influence the transverse thrust generated by the propeller.

Therefore, the transverse thrust effect is most dependent on A) Propeller RPM. The higher the RPM, the more pronounced the effect will be, as the propeller imparts more lateral force due to its rotational motion.
