Marinette, Wisconsin. She was the eighth of the fourteen Keeper-class vessels completed. The contract price for the entire class was $220 million, suggesting that the original cost of ''Anthony Petit'' was approximately $15.7 million. The ship was launched on January 30, 1999, into the
Menominee River. Speakers at the christening ceremony included Alaska

Keeper-class ships, including ''Anthony Petit'', use
z-drives for propulsion instead of fixed propellers and rudders. The z-drives may be synchronized to point in the same direction when underway. The ship is steered by changing the direction of the thrust. For fine maneuvering or station keeping while working on a buoy, the two z-drives may be pointed in different directions. These are combined with a bow thruster to allow the ship to remain at the same spot in the sea, a capability known as
dynamic positioning. The two z-drives are powered by two

3508 TA Diesel engines.
Electrical power is provided by three Caterpillar 3406 generators.
The ship has a 42-foot long boom crane capable of lifting 10 tons onto her buoy deck. This allows floating buoys to be hoisted aboard for maintenance. The buoy deck is 1,335 square feet in area.
''Anthony Petit'', as all Keeper-class buoy tenders, has an ice-strengthened hull so that she may continue to service navigational aids in light ice conditions. There is an "ice-belt" of thicker steel at the ship's waterline to resist ice damage to the hull. The bow is shaped to ride up over the ice and crush it with the ship's weight. Her performance in ice conditions varies with the quality of the ice, the amount of power applied, and other factors. At full-throttle, the ship can maintain a speed of 2 knots in smooth ice thick, but various operational considerations argue against breaking ice this thick.
''Anthony Petit'' has one ship's boat, an long Cutterboat ATON – Medium (CB-ATON-M). This boat was estimated to cost $210,000.
The ship's namesake is U.S. Coast Guard Chief Boatswain's Mate Anthony Petit, the keeper of the
Scotch Cap lighthouse on the west end of
Unimak Island in the
Aleutians. Petit and four other members of his crew were killed in a tsunami which destroyed the lighthouse on April 1, 1946.
Operational history
After her launch and sea trials, ''Anthony Petit'' sailed down the
Great Lakes, the
Saint Lawrence Seaway, and through the
Panama Canal to reach
Ketchikan, Alaska, her homeport for her entire career. She arrived in January 2000.
The ship is stationed at
Coast Guard Base Ketchikan
Coast Guard Base Ketchikan is a major shore installation of the United States Coast Guard located in Ketchikan, Alaska. The base is a homeport for two Sentinel-class cutters and a buoy tender, and is the only Coast Guard dry dock in the state. Lo ...
. She replaced
USCGC ''Planetree'' at this station. Her primary mission is maintaining 274 fixed and floating aids to navigation in Southeast Alaska.
The ship has also performed other Coast Guard missions. ''Anthony Petit'' participated in search and rescue activities as with the charter boat ''Fishin' Fool'' in 2002, fishing vessel ''Yvonne Denise'' in 2005, the ferry
''Lituya'' in 2009, and the fishing vessel ''Tsimshian Lady'' in 2017.
''Anthony Petit'' has trained extensively on oil spill containment. She has participated in several joint United States-Canada exercises to prepare for a possible spill in the
Dixon Entrance area. She has deployed the
vessel of opportunity skimming system (VOSS) several times in training.
