Variations: [Yn] Beisht [y] Kione Dhoo ([The] Beast of [the] Black Head); [Yn] Beisht Kione ([The] Beast of Head) (erroneously)
Fishermen on the Isle of Man have traditionally observed a number of customs. Whistling on board “bothers the wind” and is discouraged. Sticking a knife in the mast on the appropriate side causes the wind to blow from that direction. Losing items on board is bad luck; borrowing items from “lucky” boats brings good luck. Four-footed land animals should not be mentioned by name, but instead by a circuitous sea-name – rats, for instance, are “long-tailed fellows”. Cold iron is a remedy to most acts of bad luck.
Then there is a number of sea creatures that can wreak havoc on fishing vessels. Of the the Beisht Kione Dhoo, the Beast of Black Head, is the most terrifying. It makes its home in the sea-caves on Black Head, near Spanish Head at the southern tip of the Isle of Man. The few who have seen it say it has a head like that of a large horse, and it can be heard roaring by fishermen off Spanish Head. Some say it is the soul of a man killed by pirates in order to protect their treasure hidden in the headland’s caves. Nobody has attempted to claim that treasure.
To placate the Beisht and bring on good luck, rum is left in the cave at Spanish Head. Fishermen heading out to sea would throw a glassful of rum overboard in hopes that the Beisht will grant them a bountiful catch.
