And you base that tidbit on what real knowledge?
Even a dingy captain would wait 4 hours for a few feet clearance, but, noooooooo, that would cost a few dollars more in labor & fees.
So they we're allowed to proceed, they hit bottom & spilled "25,000" gallons.
Us dingy captains who actually live & work along the river calculated from the list & tonnage of the ship it was more like 250,000 gallons.
We told the CG who were very mad at us for even having the nerve to talk to them.
Yet, the next day they "revised" the spill estimate to our figures, go figure.
