"Sentinel of the Inland Seas"
The CGC HOLLYHOCK is a $29 million cutter that was built at Marinette Marine Corp. in Marinette, Wisc. Launched Jan. 25. 2003, she underwent fit-out and sea trials before officially taking up station at Port Huron, replacing the World War II-vintage tender Bramble. The cruise took the Hollyhock past the Bramble, now a museum ship at Port Huron. Many of Hollyhock's crew previously served on the Bramble before joining their new vessel.
Hollyhock is the 14th Juniper Class Seagoing Buoy Tender built out of a projected 16 of this class. She is 225 feet long, displaces 2,000 long tons, and is powered by two diesel engines which power a single controllable pitch propeller. Hollyhock is also equipped with bow and stern thrusters, in addition to a 20-ton hydraulic, 60-foot telescoping beam Appleton crane. She carries a crew of eight officers and 42 enlisted personnel.
Hollyhock's primary missions are aids-to-navigation (maintenance, removal and replacement), search and rescue, environmental protection and ice-breaking.
The Hollyhock's Dynamic Positioning System, which allows a computer to take control of the engines, rudder, propeller and thrusters, can hold the ship within a 10-meter circle in winds up to 30 knots and eight-foot seas, which allows pinpoint positioning of buoys. The vessel is responsible for nearly 150 aids-to-navigation on the lower Great Lakes.
