Re: How to deal with truncated transome?

Hi all,

it is a interesting question.

In my opinion it is not really a problem wich length and Displacement you use for prism. coeff.
Think about the question: How do you use these coefficients.

Most time you just want to compare quite similar hulls.

On the other hand, with your vitual hull, you get a bigger length and a bigger Displacement. Mainframe section keep quite the same cp will not vary very much.

A quite similar discussion is about Froude numbers. Wich length do you take for froude number….
For comparing similar hulls, it is only important that you always take the same length.
