In perfect (no wind or current) conditions, Panope is backed into a slip.
At slow astern speeds, this vessel cannot be steered with rudder alone. Instead, astern "steerage" is accomplished by applying short bursts of AHEAD power against the rudder that is positioned hard-over in the OPPOSITE direction...

In this video I tested the effects of having an anchor shank with a sharp leading edge. Two anchor shanks were temporarily modified, one, with the edge sharped, while the other was made more blunt. Holding power tests were conducted back-to-back, with and without the modifications.
