Fascinating - I wonder what the procedure is for a jammed propeller on a sub. I’m used to airplanes, which have redundancies for everything, but a sub propeller is really a single point of failure. Potentially seaweed or rope could become entangled, right?
Would the sub typically have to surface to manually clear the propeller? Or, does it have enough torque to just (noisily) obliterate most entanglements?
