   -15 t:  Weight reserve

Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     2,417 lbs / 1,097 Kg = 763.1 x 1.9 " / 47 mm shells or 1.2 torpedoes
   Stability (Unstable if below 1.00): 1.13
   Metacentric height 1.0 ft / 0.3 m
   Roll period: 12.3 seconds
   Steadiness   - As gun platform (Average = 50 %): 50 %
         - Recoil effect (Restricted arc if above 1.00): 0.01
   Seaboat quality  (Average = 1.00): 2.00

Hull form characteristics:
   Hull has a flush deck
   Block coefficient: 0.650
   Length to Beam Ratio: 5.00 : 1
   'Natural speed' for length: 12.15 kts
   Power going to wave formation at top speed: 62 %
   Trim (Max stability = 0, Max steadiness = 100): 25
   Bow angle (Positive = bow angles forward): 0.00 degrees
   Stern overhang: -3.28 ft / -1.00 m
   Freeboard (% = measuring location as a percentage of overall length):
      - Stem:      19.69 ft / 6.00 m
      - Forecastle (25 %):   16.40 ft / 5.00 m
      - Mid (50 %):      13.12 ft / 4.00 m
      - Quarterdeck (15 %):   13.12 ft / 4.00 m

      - Average freeboard:   14.93 ft / 4.55 m

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 52.3 %
      - Above water (accommodation/working, high = better): 95.5 %
   Waterplane Area: 3,340 Square feet or 310 Square metres
   Displacement factor (Displacement / loading): 229 %
   Structure weight / hull surface area: 50 lbs/sq ft or 244 Kg/sq metre

They could be called the "Amigo" class :)

[Sachmle]

Perhaps sim it w/ a higher speed to simulate the tremendous HP, but list it at the lower speed and claim transmission gearing for the difference.  Wikipedia (I know, not always accurate) lists larger ocean tugs as having up to 3000hp.

[P3D]

I'd use a destroyer for towing, for the unprobable case when all the two/four turbines fail. It worked in WWII with the Yorktown.

[The Rock Doctor]

That could be done, but four of these tugs, built to merchant standards, would cost less than a single torpedo-boat.  Their freeboard and range are more suitable to long-range tow/salvage work than a torpedo-boat, too.
