Note the "Prestige" is a single hulled tanker. These were banned from US waters by the Oil Pollution Act of 1990, drafted by the USCG and approved by congress, following the Exxon Valdez disaster.

...the "Prestige" is a single hulled tanker.

From the article I believe that the "Prestige" is now a double hulled tanker. Half at one place, half at another.

These were banned from US waters by the Oil Pollution Act of 1990 Actually the final ban doesn't come into force until 2015.
