Stewards' Cup
Coastal Bluff was an unusually large grey horse bred in the United Kingdom by R M West. He was probably the best horse sired by Standaan, a grey sprinter who won the Stewards' Cup in 1979 and the Palace House Stakes in 1981. Coastal Bluff's dam Conbattente showed little ability as a racehorse, but her grandmother Tina was a successful broodmare whose descendants included Rose Dubarry, the leading juvenile filly of 1971 in Britain and Commanche Court.
