The Coast Guard Cutter Red Cedar (WLM-688) was one of five 157-foot coastal buoy tenders built by the Coast Guard Yard that entered service between 1964 and 1971. They were the first new class of seagoing buoy tenders of the post-World War II era that were designed and constructed by the Coast Guard. This class of tender was designed to service aids to navigation up to 10-tons and, with a draft of only seven feet, to operate in shallow waters often encountered on the sides of dredged harbor channels. Each tender was assigned to tend aids to navigation in coastal waters while being "always ready" to carry out other traditional Coast Guard duties such as fighting fires and conducting law enforcement, environmental protection and search and rescue operations when required.
