Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 129.9 %
- Above water (accommodation/working, high = better): 117.8 %
Waterplane Area: 2,506 Square feet or 233 Square metres
Displacement factor (Displacement / loading): 118 %
Structure weight / hull surface area: 29 lbs/sq ft or 141 Kg/sq metre
Hull strength (Relative):

Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is adequate
Ship has slow, easy roll, a good, steady gun platform
Excellent seaboat, comfortable, can fire her guns in the heaviest weather

Notes: Static training ship in Cobh. Scrapped late 1943.
