Rick is absolutely correct. Coral reefs and large cruise ships are incompatible.
I haven’t updated my weblinks on this issue for a few years. Let me see what I can dredge up (no pun intended). I only look into cruise ships and coral reef ecosystems as *hobbies* that supplement my regular job.
Here is a (lengthy) citation listing regarding cruise ships and the environment.

Other citation listings for use by researchers and other interested parties can be found from the main site.

Which in turn is linked from this website, which compiles all sorts of interesting facts and figures for the industry. It’s normally “one-stop shopping” for me when I need hard data.

“Accidental” releases of wastewater are believed quite common, but rarely documented. Here’s a good example of one that was.

Unless someone keeps on eye on them, all that fancy pollution control equipment aboard (newer) cruise ships is often turned off, or broken.

The ecotourism journal Planeta released this commentary over a decade ago. Its main premises still stand today. Take particular note of the section titled “COMPETING FOR TOURISM PROFITS: THE FALLACY OF DEVELOPMENT”

For a good summary of cruise ship effects, the non-governmental environmental watchdog group Oceana put this reasonably accurate report together (in 2003). No, Oceana is not some crazed eco-hippie group. They aren’t making this stuff up or incredibly exaggerating their figures.

For the science nerds, here’s a research article describing problems Jamaica is having as a result of poor water quality. If Bonaire gets cruise ships, it’s a foregone conclusion that shipboard sewage will either get dumped into your local infrastructure or unobtrusively dropped into your local waters. Cruise ships are unable to store all their sewage onboard for very long; they are not closed systems.

These are just a few example websites or reports. For more, just run a Google search using the keywords “cruise ship pollution”. You should get a mountain of hits. Read them at your leisure... or horror. Its been my observation over the last several years that virtually no one has any knowledge about how cruise ships work or their operational policies. This includes legislators, and city managers.
A handful of Caribbean nations have some attempts towards cruise ship regulations in place. It might be useful for Bonaire managers to analyze what places like Bermuda or the Cayman Islands have implemented.
