Folks,

 

I have not come very far in my design process except for working throu the hull design and structural engineering factors.

 

I am wondering how you maintain a low centre of gravity so that you stay upright all the time whether with full ballasts or empty, when the ballast tanks on the photos I see seem to be placed anywhere from above centre or below?

 

Regards, Iain.
