The Ger/CB/1912 in Springsharp 3.0b2 Beta

The Ger/CB/1912 design seems like a natural for Springsharp 3.0b2 Beta, as it has inclined side armour. I do have a photo of one of the ships, as well:

This is a 32 knot ship with 6-15in/45 and 8-6in QF guns. The ship has a thick deck to go with the inclined side armour, so that despite the thin torpedo bulkhead, the ship is well-protected for a ship with thin side armour. This is the Springsharp report:
