The Scilly naval disaster of 1707 was the loss of four warships of a Royal Navy fleet off the Isles of Scilly in severe weather on 22 October 1707. Between 1,400 and 2,000 sailors lost their lives aboard the wrecked vessels, making the incident one of the worst maritime disasters in British naval history. The disaster has been attributed to a combination of factors, including the navigators' inability to accurately calculate their positions, errors in the available charts and pilot books, and inadequate compasses.
The Western Rocks are a group of uninhabited skerries and rocks in the south–western part of the Isles of Scilly, United Kingdom, and are renowned for the numerous shipwrecks in the area and the nearby Bishop Rock lighthouse. In 1971, the rocks and islands were designated a Site of Special Scientific Interest for their breeding sea birds. Landing on the islands is both difficult and discouraged and there are few published records of visits by naturalists.

Recreational dive sites are specific places that recreational scuba divers go to enjoy the underwater environment or for training purposes. They include technical diving sites beyond the range generally accepted for recreational diving. In this context all diving done for recreational purposes is included. Professional diving tends to be done where the job is, and with the exception of diver training and leading groups of recreational divers, does not generally occur at specific sites chosen for their easy access, pleasant conditions or interesting features.
