Exact same thing happened to me over xmas. Guy strolls up with a shiny new Kontiki, which he obviously had just brought and parks himself slap in the middle of me and another rod fisherman. Big swell running across the beach, he sets his line out about 500m, which of course then gets dragged up the beach taking out the rod fisherman next to me and a bunch of kids swimming. Firstly I dont entirely like the use of these things, but even more I dislike People who dont have a clue on how to use them, and fail to recognise the consequences of their lack of knowledge.
