The drawings in this directory (tanks) were provided to me by Tsai at the Tayana factory.  They are the drawings for the tanks that are in my boat which is hull number 581.  

These are scans of the paper drawings.  I do not have CAD files for these drawings. 

I suppose its safe to assume that they are the same (or very close to the same) as the tanks in other boats but there are no guarantees. 

Harvey suggested I post them here as they might be helpful to someone someday.
