USCG Coastal Buoy Tender
From Wikipedia, the free encyclopedia
The United States Coast Guard commissioned a new Keeper-class of coastal buoy tenders in the 1990's that are 175 feet (53 m) in length and named after Lighthouse keepers.
These vessels and the 225 feet (68 m) Juniper class of seagoing buoy tenders replaced the World War II era 180' Seagoing Buoy Tender.
They were the first Coast Guard cutters equipped with Z-drive Azimuth thruster 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.
