SHIELD
Blue, white and red are the colors used by the Coast Guard. Light blue has been adapted from the Coast Guard seal. The dolphin symbolizes the tradition of assistance and support given to ocean travelers by Coast Guard personnel and the mission of protecting the environment and the ocean habitat. The wavy tripartite bordure highlights the three vessels named for Salmon Portland Chase. The bezant symbolizes Chase's appointment as Secretary of the Treasury to Abraham Lincoln, and bears a representation of the first cutter to be named Chase.
CREST
The demi-trident signifies authority at sea, the tines representing the three Coast Guard cutters to bear the name Chase. The laurel wreath refers to the many honors awarded to WHEC 718. Secretary Chase's early career in public service is recalled by the red annulet, adapted from the flag of the State of Ohio of which he was twice Governor and twice elected Senator. The broken chain represents freedom underscoring Secretary Chase's vigorous opposition to slavery and his zealous defense of runaway slaves in the courts of Ohio. The gavel represents Chase's most prestigious political appointment as Chief Justice to the U.S. Supreme Court and denotes authority and justice. Red signifies courage and sacrifice; gold is for excellence.
