Yes, there is a long storage area above the IP35 Quarter Berth that runs behind the cockpit seats. Many have cut an access panel into this space at eye level when standing in the Qtr berth. I know there are photos of this, but I can not find them right now. I have looked into one of these opened up area and it is rough fiberglass. What I have seem others use this area for is fishing rods and boat hooks and long board storage. I guess you could put a bag of laundry in there as well, why not.
I have seen some frame out the cut out with teak and add a teak door. Some use a plastic hatch lid and cut it and screw it down.
We have not cut this access in, as we fell we have too much stuff on the boat already and this would just give us one more place to fill up
