Not sure Bruce but am willing to bet the lady in the Silverton is game to give it a go if she had some.
Slight hijack. Sydney Harbour, a big secure harbor with 100,000 ton cruise ships visiting, has the "Sow and Pigs" reef mid harbor. Breaks at low tide and has 4 cardinal marks all around it. Occasionally the inevitable occurs, normally a pleasure boat not looking or racing sailboat pushing the margin, I know a very embarrassed ex Navy sailboat owner who has done it. Were I Harbour Master I`d consider dynamite, but the fish, environmentalists, and fisherpersons might have other ideas, and who knows what losing it might change.
Could dynamite fix the Rockpile?
