What is the process to build a artificial reef legally?

I know where there is a derelict 60 foot small wooden trawler, stripped of mechanicals but afloat, that you could load with ballast then tow with your boat. If it just happened to sink behind the Vineyard I doubt there would be much red tape involved.

A ship has to be made completely sterile, wooden vessels need not apply.. I watched the feds sink a carrier somewhere in the last few years. It took a lot of dynamite to get it down.
