Thanks for all the ideas. This wreck is only 100ft long and that was when it
was still afloat, it's also in deep water 265ft and it also has reef near it
so it can be easy to miss it and get reef instead as we have found recently.
I'm sure with all these ideas we should get it next time.
Thanks again.
