My foil is smooth and soft and rounded. I think it's gorgeous.
Because I need deeper water I stay well away from areas where there are people. You have to be fairly competent just to ride a foil so the chances of careening out of control are slim.
More importantly, we hear about bans, but they never seem to appear. I think councils have better things to do than to ban fringe activities that rarely happen. The paperwork wouldn't be worth the effort.
The Daily Mail is not known for reliability or quality journalism. It begs the question of how they could be bothered to write a story about something that is of such little interest to the general public. I'm guessing the availability of a photo of a woman in a bikini on a foil might have something to do with it.
