When the dust storm hit the ship was in a canal with sloping sides, 313 meters at the surface and only 121 meters wide at its deepest. At Ever Given’s draft, the effective channel width was just over 200 meters wide.
Starting with the ship’s beam at 58.8 meters if the Ever Given is in the middle of the channel she has about 70 meters on each side.
Take into account sweept path due to leeway:
With 4 degrees of leeway and a 4 degree course change for a total angle of 8 degrees to regain the center the effective beam of the Ever Given would be about 120 meters. 200 meter of channel - 120 meters of effective beam means all but 80 meters of the channel width is required or 40 meters on each side if in the center.
Not much room for helm or pilot error in gusty winds.
