"Narco sub" carrying 8,000 pounds of cocaine intercepted in Pacific Ocean, Mexican Navy says

The Mexican Navy said Tuesday it has seized 3.6 tons (about 8,000 pounds) of cocaine aboard a "narco sub" off the Pacific coast which was spotted earlier this week about 153 miles off the resort of Acapulco.

Navy ships arrived to intercept the boat, which was carrying 102 packages filled with bricks of cocaine, authorities said in a news release.

The craft, of a type known as "go-fast boats," was powered by two outboard motors and appeared to be a low-profile, semi-submersible craft -- commonly known as a "narco sub" -- designed to make detection more difficult.
