What self-respecting sea creature would turn down four staterooms, a spacious salon, and an elevated helm station? I'm in New Orleans, we have very successful artificial reefs in Lake Pontchartrain and the GOM. Successful in that each has matured quickly to promote and support incredibly healthy, diverse, and beautiful marine life. Ever dive on an oil rig? Not the first thought as a source of beauty but amazingly healthy ecosystems all on their own. I don't claim to be an artificial reef expert by any means, just thinking of the mass of material that will need take up space somewhere, why not something cool and productive on an otherwise barren seabed?
