Port officials and operators are none to happy about a likely new rule that big ships must slow to 11.5 mph when near right whale migration paths.
Though the whales can grow to a massive 60 feet and 100 tons, that's only 6% the length of a relatively modest Panamax cargo ship.
But port operators say the policy unfairly targets Charleston and is far too costly in slowed business.
