This Deadly Jet Boat Is a Pirate's Worst Nightmare

Wild. I designed a larger ship using the same concepts. Estimated top speed was 110 knots. Mine was a bit bigger, 240 foot by 80 foot beam. Still want to build it.

From the article...

"The good news is that, once complete, it could be made available to private customers."

Customers like drug traffickers, or pirates?

Would seem a lot simpler to just take a couple of cargo ships or some old Navy supply vessels, repaint them and outfit them like the old Q boats and start sailing around the area. When the pirates make their move take them out with 50 caliber or 20 millimeter rounds.

A couple of old 40mm pom-poms would do wonders on reducing the pirate fleet and instilling some fear in the pirates themselves, maybe even enough that they'll find jobs ashore.

Since you want them to attack in International Waters to verify their piracy attempt you don't really need a shallow draft vessel. The Q boats killed enough submarines back in their day and the technology and necessary weapons are readily available to make them even more deadly and effective.
