Are there trade mags which discuss how effective different products are? If these Yacht owners are like I imagine, they fling open-checquebook rights to some flunkey and they install one, but they also like bragging rights and I am told can be obsessive about "how they chose the best" even when somebody else did it.

So what's the go-to bible for ranking anti-drone fitout for superyachts?

Why would a yacht need a counter-drone system?

One use-case I can imagine is to ward off tech-savvy paparazzi.

They have drones that will go out to sea? I thought the amateur stuff you needed to be line-of-sight.

Line of sight over water is quite a long way, and pleasure vessels spend most of their time near the coast.
