Overall survivability and seakeeping ability:

Seaboat quality (Average = 1.00): 1.89
Hull form characteristics:
Hull has a flush deck
Block coefficient: 0.750
Length to Beam Ratio: 5.71 : 1
'Natural speed' for length: 20.00 kts
Power going to wave formation at top speed: 41 %
Trim (Max stability = 0, Max steadiness = 100): 37
Bow angle (Positive = bow angles forward): 0.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 20.00 ft / 6.10 m
- Forecastle (20 %): 16.00 ft / 4.88 m
- Mid (50 %): 16.00 ft / 4.88 m

- Stern: 16.00 ft / 4.88 m
- Average freeboard: 16.32 ft / 4.97 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 69.2 %
- Above water (accommodation/working, high = better): 124.7 %
Waterplane Area: 23,451 Square feet or 2,179 Square metres
Displacement factor (Displacement / loading): 169 %
Structure weight / hull surface area: 124 lbs/sq ft or 605 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 1.47
- Longitudinal: 2.30
- Overall: 1.53
Hull space for machinery, storage, compartmentation is excellent
Room for accommodation and workspaces is excellent
Ship has slow, easy roll, a good, steady gun platform
Excellent seaboat, comfortable, can fire her guns in the heaviest weather
Tenders ought to have high freeboard, so there's room for workshops and accommodation. Since you've got ample hull strength, raise freeboard up to ~8 metres or so...
You mean like this?

That's a little more than I had in mind - I meant the actual freeboard should be in the seven to eight metre range. It'll leave some hull strength left over - you could then increase miscellaneous weight some.
Oh.
So this then would fit better?
