There's no study, but I can say that there's no engineer in the world that could come here and give any more evidence than what the three people sitting here could give. We've watched it since we were kids. If you look at the top picture in Naufrage Harbour and you look at the east pier, or the pier on the right going out, you can see that it's in the breakers and just barely at the top of the shore. It's just common sense to say that it's going to fill in; you'll have to get out farther.
In my opinion, the structure was designed wrong originally. Having a lot of experience with how sand works around currents and tides and moons and stuff, the sand travels from west to east, because the prevailing tide is going east. If the east structure was out parallel with the west structure, what would happen is the sand would go by and land east of the east structure, which is out of our way. That's common knowledge to the fellows that are there and see it all the time.
