When he introduced himself he said he was "Paul and I am the water safety guy in the Trossachs."
Water Safety Scotland has many voluntary individuals who are there to engage and educate to help prevent water related fatalities. Water Safety representatives will be found at all locations where the public gather and could put themselves in danger - and therefore others who may have to be involved in a rescue. In our area most people who run water based sports are also 'local' Water Safety representatives.
The bye laws of Loch Lomand state that 'personal watercraft' users have to use buoyancy aids so that could be interpreted as banana boats as well as it could potentially relate to any means of conveying a person on the water. We have two good friends who are paddle board / surfing instructors and business owners and the first lesson you must take involves safety. We live by the sea in Scotland and children are brought up knowing the dangers, how to read the tides and keep themselves safe. I have to say that any fatalities that there have been in our area over the years have not been locals. A visit from this gentleman to advise them on water safety and the fact byelaws were not adhered to was nothing to the bollocking he would get here from one of the RNLI volunteers if he arrives near us to paddle board without buoyancy aids.
Lochs look beautiful and safe in comparison to the sea but just as you can find a vertical face on a mountain, so you can find vertical drops in lochs and Loch Lomond the depth can go down to almost 160m. Even in the warmest of days the water of the lochs can be freezing and shock sets in quickly. No way if the girls were some distance from shore or from Chris, and one of them fell in to a colder stream in the water, would the other one be able to haul them out of the water and get to safety.
Lockdown has seen a surge in paddle boards owners which is lovely that people are out enjoying themselves and nature - my son had a pod of dolphins join them on a sea paddle a couple of days ago - but this is not a swimming pool you are taking a board for a wee paddle on.
Also if the Inghams are saying that the campsite owner was unaware of byelaws ( only going by other comments on here ) then they have completely landed him in it !
Finally, don't give a toss if you think you are famous ...' famous' people drown too.
