Well, perhaps I was being too specific.
I was thinking: Search and Recovery, Visual Inspection of Swimming Areas(ie: glass,) Prop-Disentanglement (I do have serious concerns here, do props have a habit of "springing" into rotation when freed? (Granted Sparks would be pulled and whatnot...) small boats like one would find in a pond, not 100,000t displacement vessels..) Swimming Buoy placement. Also perhaps as someone mentioned, lake mooring (re)placement (not 1000lb blocks!). Smaller stuff.
Perhaps I was thinking too too advanced.
