Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
477 lbs / 216 Kg = 7,1 x 5,1 " / 130 mm shells or 0,2 torpedoes
Stability (Unstable if below 1.00): 1,45

Excellent accommodation and workspace room
But thanks anyways. Reading another report of the same ship had me re-checking this one, and correcting some minor errors.
