The Royal Adelaide was an iron sailing ship of 1400 tons built by William Patterson at Bristol in 1865. She was wrecked on Chesil Beach on 25 November 1872, while on a passage from London to Sydney with a crew of 32 and 35 passengers. In bad weather, the ship tried to reach the shelter of Portland Harbour, but was forced into Lyme Bay from which there was no exit in a storm. The anchors were lowered to try to prevent the ship being blown onto Chesil Beach. However, the anchors dragged and the ship began to break up on the beach. All but six on board were saved.
