Post# of 8054
great circle distance from 31.86 N 116.6 W Ensenada and 29.867 N 121.55 E Ningbo is 5849 nm
assuming a direct course from Ensenada to Ningbo ---ship left May 19 w ETA Ningbo June 11- ca 22 days which is a speed of 11 knots,which is to be expected w occasional rough pacific ocean conditions and a full load at 13.7 meters draft-max speed of ca 14.2 w normal unloaded 7 meter draft cruising speed ca 12.5 knots-original ETA was June 9 so rough weather probably slowed ETA
that does not leave any time for a mysterious ghost journey up but far off the coast to Portland-assuming June 11 Ningbo ETA is correct info
