"2 x Single mounts on centreline ends, evenly spread" is that right? Should it be twins?

Seakeeping:



Seems good enough to me.

Good catch. Fixed.

   Seaboat quality  (Average = 1.00): 0.35

Hull form characteristics:
   Hull has raised forecastle,
     a normal bow and a cruiser stern
   Block coefficient (normal/deep): 0.705 / 0.710
   Length to Beam Ratio: 3.83 : 1
   'Natural speed' for length: 15.17 kts
   Power going to wave formation at top speed: 51 %

   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 72.6 %

   Excellent machinery, storage, compartmentation space
   Extremely poor accommodation and workspace room
   Caution: Lacks seaworthiness - very limited seakeeping ability
You smug-faced crowds with kindling eye
Who cheer when solider lads march by
Sneak home and pray that you'll never know
The hell where youth and laughter go.

Looking at that picture, the "Ship tends to be wet forward" remark in the SS data makes me laugh. It's wet everywhere! ;D
