Having worked on a production platforms out in the Gulf, I can say transfering from a simi rigid platform to a boat is not a safe or simple thing to do. Can imagine how dangerous it would be to try an transfer inexperienced people from one moving boat to another boat.
I can just imagine how happy the lawyers would be if someone was injured in this transfer.
The sewage problem probably could have been solved if the sewage was just dumped overboard. Now again the EPA and a whole bunch of agencies would sue the the boat owners out of business. The regulations are so strict that the boat porbably didn't even have a means of dumping the sewage.
