ECHT production company was presenting a documentary film ‘Searching For Sea Monsters’ and had journeyed up to the far north Caithness coastline to build an eco-raft from found plastics and other debris they recovered from Dunnet beach. They were filmed by James and Alston as they searched for the mythical sea monster known as the Kraken – which they hoped to encounter in the choppy waters of the Pentland Firth.
