It is always a good Idea when they do this. I wish they sunk it in a little shallower water though. As a diver it is a little deep for a nice long relaxing dive (212') ans forget about any coral or photosynthetic life. But that is trival, I am glad they sunk her for that purpose.
I have been trying to get tires dumped in the sea for years for the same purpose. We have millions of tires with no use for and thousands of miles of seabed with no topography but mud. I have been diving for lobsters in the Long Island Sound for almost forty years and almost every sunken tire contains a lobster. Lack of reefs, either natural or man made is IMO the biggest obstacle to increasing sea life. There is almost no life on a mud bottom besides worms but add a tire (or aircraft carrier) and a whole new world opens up.
I know this is off subject, sorry,
Have a great day.
