Tranverse thrust - effect on single screw, twin screw, and controllable pitch propellers

This is video 10 in the series of videos on ship handling.

Thanks. Been looking for this explanation for a week.

You are most welcome 😊

In the initial stages of the ship getting underway, the vessel’s speed is low but the engine (and, therefore, the propeller) is at high Rpm ahead.
During this period, the transverse thrust is directed to starboard and the ship’s turns to port. Please note that as the depth increases, water pressure increases, therefore there will be difference in pressures on top and bottom of the propeller blade. This is due to the fact that the pressure from the water is higher on propeller blades in their deeper position than in their shallower position. As the water above develops turbulence and the air is sucked in which reduces the pressure on the top blade. As the ship gradually increases the headway, the turbulence is reduced and the pressure on the top blade increases.

How transverse thrust effects on Right handed CPP

Thanks.. Great help..

You are most welcome:)

Good

[@rajivsingh4898]

sir the right handed fixed pitch propeller will have turning circle greater or smaller on which side(stbd or port)?

[@SteeringMariners]

will try and make a detailed video on it soon

[@rajivsingh4898]

sir can u take session on balanced, semi balanced and unbalanced rudder?

[@SteeringMariners]

sure...I will try my best:)

What Does "CANT" mean
Like Cant to port/STB
