Phish and Spinner

Click here for the latest on the prototype!
There are two variations of the craft:
(both top AND bottom harnesses are optional, this drawing is from my 2nd prototype, presently being 3D printed)
 Sub-Sea Spinner
The essence of both, whether large or small, is a "Torque Reaction Engine" ("TRE"). The TRE is sealed within the hull.  No driveshaft punctures the hull.  The craft swims like a fish, with extreme economy. 

The fishBOAT is patent pending (PCT/US14/68572: drawingsspecification).

What is this craft good for? Here are some notes.
