Peerless or clueless captain at scene.
After 03 minutes 30 seconds exercise time lapsed:
Ownship speed is 15.3 knots which had decreased from 16.3, 18.0 kts with engine output 79% from beginning. Ownship course had altered 15 degrees port side to 063.5 degrees from 078.5, 063.8 degrees with rudder angle “starboard 20”/“Hard Starborad”one minutes and “Hard Port” over one minute. The
situational awareness is:
Ownship reduced speed slowly with hard over rudder order. (sighted with one knots lesser) Ownship might do rudder cycling maneuvering now. (suspect) One minute on “hard Port” after one minute on “Hard Starboard”/”starboard 10”is OK. (sighted) Hard over Rudder angle is not necessary come with lost control of ownship. (sighted) If this is not rudder cycling, ownship is incompetent in shiphandling. (statement) Turning rate “10 degrees per minutes” is Ok for this type of vessel. (sighted) Port side crossing vessel is about to pass now (orange square). (sighted with sharp course change to port side again) One overtaking vessel at starboard side passed ownship bow (orange square). (sighted.) Crossing vessel at starboard side will pass after 3 minutes (red circle). (skill by estimating 3 minutes vector) One crossing vessel at port side is about to pass ownship bow after 4.5 minutes (yellow circle). (skill by estimating speed vector direction)
