This is, as has been said, an act of pure spite.
Why on earth would anybody stoop this low just to prove a point?
This handy work was as a result of a dispute between genuine customers, Tom and Jan, and Ben Harp Narrow boats. You can read more about this sad state of affairs on Nb Waiouru blog site. I feel truly sorry for Tom and Jan, and I admire the fact that they have brought our attention to this despicable behaviour. I don’t need to prattle on, as the photograph speaks volumes about the individual that did this, a good advert indeed....enough said.
