What a tender for ten Sunderland flying boats would require

How would a seaplane tender support ten Short Sunderland flying boats?

Provide fuel and stores, a low stern or ramp for access in suitable weather, and ramp-equipped lighters to retrieve aircraft needing repair.

The proposed tender carries plenty of fuel and stores for ten Sunderlands. A low freeboard aft would let aircraft come alongside for direct transfers in safe weather. A ramp at the stern is also considered. One or two lighters would retrieve aircraft in difficulty and return them for maintenance or repair. Those lighters would need a ramp arrangement capable of bringing a Sunderland aboard. The answer sketches access and recovery arrangements rather than specifying cranes or a complete workshop inventory.
