“We are not the only vessel on the water and if someone inspected a jet-ski they would see for themselves that it has no propeller or rudder, making it a very safe vehicle on the water.

“There are more boats compared to jet-skis using the Tay. Boats range from small fishing boats, and speedboats to large cargo boats — all with engines using a propeller and rudders. As you can imagine, the propeller turns at great speed and can shred any item that comes in contact with it.

“Dolphins and seals are able to detect objects on the water and, as we are smaller, then it is easy for them to dive under or around a jet-ski.

“With regards to jet-skiers making off towards the dolphins, I do agree we do go out and view the dolphins, but we spend only a short period of time viewing. It should also be noted that no vessel on the water can go where it likes, and a bystander on the shore would probably not be aware we have set channels for leaving and entering the shore.

“This could look as if we are heading straight to the dolphins as they tend to be in the deeper channels and away from the shore, but we have to be set-distances from the shore and also within marked areas, as per the bylaws.
