I sail in a limestone rock quarry. It's 20 acres with crystal clear water. I stand on a 10 foot ledge and can see the sub as deep as I go. I lost a DeBoer Skipjack in 40' water there but I was in luck as 20 divers from the local rescue squad were there training. They found it in 20 minutes. The WTC didn't leak either. Too much weight and as I hovered and took my attention off her she sank.
