The Round Britain and Ireland double handed Yacht Race was established in 1966 and is held every four years starting and finishing in Plymouth, England.
There are four compulsory stops of forty-eight hours at Galway, Barra, Lerwick and Lowestoft.
[1] Following the success of the first two OSTARs, Herbert Hasler proposed to the Royal Western Yacht Club that there should be a two-handed race around the British Isles.
The course, of about 2,000 miles (3,200 km), was split into five legs separated by compulsory stop-overs of 48 hours each at Crosshaven in Ireland, Castle Bay, Barra in the Outer Hebrides, Lerwick in Shetland, and Harwich on the East Coast.
The RB&I grew rapidly to a multinational entry of many boat sizes and types.
