NOAA goes diving for U-boats in North Carolina

Divers on the National Oceanic and Atmospheric Administration's new 41-foot catamaran were geared up and waiting to descend to survey the U-701, the most intact of discovered U-boats sunk off the North Carolina coast.

Boat captain Chad Smith, NOAA's East Coast vessel coordinator, slowed the catamaran's motor and circled the position above where the wreck lay mostly buried on the ocean floor about 22 miles off Avon.

"All right, guys, start moving toward the stern," dive master Tane Casserley said to the five divers. The boat's motor was cut.

"Dive, dive, dive!"
