USCG Coastal Buoy Tender
From Wikipedia, the free encyclopedia
The United States Coast Guard is commissioning a new Keeper-class of coastal buoy tenders that are 175 feet (53 m) in length and named after Lighthouse keepers.
These vessels and the new 225 feet (68 m) Juniper class of seagoing buoy tenders replaced the World War II era
They are the first Coast Guard cutters equipped with Z-Drive propulsion units instead of the standard propeller and rudder configuration. They are designed to independently rotate 360 degrees. Combined with a thruster in the bow, they give the Keeper-class cutters a lot of maneuverability.
With state-of-the-art electronics and navigation systems including Dynamic Positioning System (DPS) which uses a Differential Global Positioning System, and electronic chart displays — these buoy tenders maneuver and position aids more accurately and efficiently with fewer crew.
