When Dad used to sail his boat in the Caribbean, he kept a spent LAW on board, just in case someone decided they wanted HIS boat. (I do NOT know where he got it. I do not WANT to know!)
I LOVED firing those things at tanks during training ops back in the day. They blowed up REAL GOOD. :)

Pretty sure you can get them at any military surplus store or show, they aren’t illegal to own or sell.
They used to sell them at gun shows out here in the West.
