Hi again,

I have added the wreck of the "Otavi" in the post above this one. While not on the Skeleton Coast, it sits in a similar setting in Namibia. It turns out that there are significantly less wrecks in the Skeleton Coast than in some other places, such as the coast of Mauritania. In fact, I haven't been able to locate any more. If anybody wants to give it a try, here are some handy maps and photos of the sites:

Good luck!
