I like kayaking, don't get me wrong. It's just you have to keep paddling, like, all the time. So big thumbs up to Devon vet Rupert Kirkwood who has found an alternative - get a tow from a shark!
Ok, it was unplanned and he's yet to work out how to direct it, but the idea is definitely worth further study. As reported at the BBC here, he went out in his sea kayak to go fishing, caught himself a tope shark and then it towed him half a mile or so.
So what's it like being dragged out to sea by a shark in a little plastic kayak? "Fun" of course, though he did admit its nose "came to within inches of my sensitive parts."
Hmmm..... further research definitely required into the safety implications of this form of propulsion.
