The Gurkha operating it on the cruise ship, suffered from splinters, so I guess they were trying.

I doubt it. Getting hit with this thing is more than a loud noise, it would rattle your head like a firehose, at close range.

That's why I'd rather just let a submarine lurk quietly in the area.

Pirate boat comes. Sub launches a torpedo. Pirate boat breaks in half and sinks without ever knowing what hit it. Sub resumes lurking down below.

The "area" is thousands of square miles, and trying to hit those speedboats with a torpedo would be like trying to shoot fruit flies with a rifle.
IF, the sub was in the right place, at the right time, a deck gun would have a better chance.
I think aircraft is a better choice, but the ship has to hold them off long enough.
