JPHART:

exactly. It is a whole new thing starting from the beggining with a new hull.

The location of rudder is pretty much the same. I am using the same fin area and shape configuration that in my prior model that is running quite well. , but the thing is in first place if i need to use in place the rudder and fin in the hull to find its center of lateral resistance??

Once this first step is clear to me, the following is just a trial and error.

Thanks
