How could sinking a ship to create an artificial reef address the problem?

Sinking a ship is not as simple as waterlogging it and letting it crash to the bottom. Many an artificial reef has been listing as it sank, and while that might not ruin the project, it throws much of the engineering off-kilter. So planning the actual sinking is intensive.

It takes about six to eight hours to get a ship the size of the Lady Luck (324ft) to sink. Once it actually begins to fall, it only takes a minute for it to hit its final resting place 130ft below the surface. Once scuttled, the wreck is open for certified divers to come and explore, as marine life takes over and begins to transform the ship into a functional part of the ocean's ecosystem.
