In my past career, I built artificial reefs by sinking ships and concrete pipe among other materials. Back in the early 2000's New York City decided to dispose of some of their obsolete subway cars by deploying them to build reefs. They were distributed down much of the east coast, and there were lots of them. Here is footage take in South Carolina, it shows the cars going in water, soon after they hit the bottom, then 3 and 10 months later. Don't miss the big sea turtle:
I proposed a similar project for Aruba, but sinking ships and barges. It didn't get off the ground. Watching this old footage, maybe I'll propose it again, including specialized snorkel habitat for Kent and the gang.

Good to hear from you, man. Before you know it, you'll be back at Mango Alto.
You are correct, prepping a ship for deployment as a reef is labor/cost intensive, but not as expensive as you might think. Here are links to a couple of ships I sank in New Jersey for this purpose. We prepped and towed them for much less money than you would imagine, and if the vessels were sourced from Venezuela or Colombia the cost could be controlled because there are different small ports there where the majority of the work could be done ahead of time.
