If you’re sick of having your favourite break cluttered up with other surfers, cry wolf on the Men in Grey Suits.
It may be a while before you can buy a shark drone like those developed by the U.S. Navy
, but there are other ways to use the fear of being devoured by a top ocean predator.
While pointing and yelling “SHARK!” would not be fully effective or sufficiently anonymous, you could post fake warning signs, like those created by enterprising surfers in California
Alternatively, strap a shark fin
to the back of a buddy and have her swim it Jaws-like past the lineup to clear it just for you.
