That answer is correct, and right now they need a permit to put it in.
If you can envision something that's two feet high in the water on a twilight evening, and a water skier coming through into a bay, and this thing is not marked, but stained in a nice dark colour with preservative oil, it is probably one of the most dangerous pieces of equipment that could be put in the water. Indeed, these things do require a permit.
It's not something we would be looking at towards minor work at this point in time, I would suggest.
