The best-known story from Bøur tells of a dispute about succession to property. Two brothers, Simun and Eirikur, owned all the village property jointly, but Eirikur was keen to have it divided. In the end Eirikur killed his brother, and then travelled over to Kirkjubøur to beg the bishop for mercy. The bishop was inclined to grant him absolution if he paid a large penalty to the bishop and to the church. Eirikur agreed, and the contract was carved out on a wooden beam.
Eirikur sailed back to Bøur, but when he reached the still waters and thought he was out of danger, a great wave rose up, the boat capsized, and he was drowned. The hidden reef has been known ever since as Eiriksboði in memory of the event, and is situated on the inner side of Tindhólmur.
