Catamaran Wave patterns for froude number 1

Comment on what you observe in figure 3 and 4. What changes there are when running from deep water to shallow water.

 

You should have a read of this simplified explanation HERE.

 

Hello,
Thank you for your answer.
I am dealing only with froude number 1, how can I compare those wave patterns?

 

It seems you didn't understand the link....as your question is self evident once you understand the basics.

Then may I suggest you read a book on hydrodynamics.

 

Hello, Can you please answer me one last question?
Why super-critical flow I have shallow depth and for sub-critical I have deep depth?

 

Because you are misunderstanding the reference to Froude number.
There is Froude number - for the vessel.
And there is Froude depth for the wave.

The two are different and you are conflating the two as one, they are not.
