Hanse 350 bulkhead

Does anyone know the construction of the wall/bulkhead between the saloon and the portside stern cabin?
I need to route a cable through and no cable duct!!!

I guess Hanse owners website might be a source of info -known as myhanse -I guess if no pipes/wires in panel a thin drill bit is your friend though
