Not Kelt related but fascinating:
French artist Julien Berthier has designed a fully functional boat to look as if it is sinking. The 6.5m (21ft) yacht was cut in half with a new keel and motor added so it remains in the sinking position while being fully functional. He describes it as "the permanent and mobile image of a wrecked ship that has become a functional and safe leisure object."
Berthier has taken the boat (or should I say half-a-boat) across the English Channel to London and has toured it around Europe , getting plenty of offers of assistance from unwitting good Samaritans, who would presumably be either very annoyed or rather bemused by the contraption.
