Hot & Cold water hoses 1999 Bene 411 2-cabin

[Jimpitt]

Hello All. This is regarding a 1999 Beneteau 411 2-cabin. We are trying to figure out how the cold & hot water hoses runs from the T just after the pressure tank & water heater located on the starboard side under the settee over to the port-side head. The hoses duck behind the galley lower storage cabinet and re-emerge from behind the head's shell in a loop under the head's sink. We've looked everywhere we can think and now suspect that the hoses are running inside the hull's structural grid. Can this be? Can somebody please shed some light on this issue? Thank you.
