SHIELD
Blue, red and white are colors associated with the U.S. Coast Guard. Gold is emblematic of honor and excellence. The rampant horse highlights the famous wild horses on the island of Chincoteague, Virginia, after which the cutter is named. The horse or caballo also plays off of the motto. The gold wreath honors the USCGC Chincoteague's history of high performance. It has won the Coast Guard Foundation Award two times (was nominated three years in a row). The polestar represents direction, guidance and the cutter's search and rescue mission. The fasces, symbol of authority, is for the cutter's illegal immigration interdiction and counter drug operation missions. The border symbolizes unity with its color red signifying courage and zeal.
CREST
The USCGC Chincoteague is based in San Juan, Puerto Rico. The El Morro Castle and its turret is one of Puerto Rico's most famous icons. The castle represents defense and strength. The two stars commemorate the two previous ships named "CHINCOTEAGUE."
SUPPORTERS
The NCO and Officer's swords are crossed for cooperation and the defense of the Homeland.
