Shelving in lockers and cabinets make better use of space in the upper areas of these cabinets.
There is alot of wasted space above the hanger rod in the master stateroom starboard side hanging locker. Adding a shelf makes for convenient space clothes or shoes.
The space in the guest stateroom is shallow and vertical, making it difficult to stack clothing of linens. Adding a shelf here, helped make the space easier to use.
