I don’t have a lot of experience reading wrecks like this, even with this high-frequency shot. Do you know if this might be indicative of a ship that burned, with the hull nicely intact, or is there no way to tell?
A fireship, or any other vessel that burned, would likely have burned to the waterline, which would leave no deck beams that we see on the image.
Now that we know that this image is of another vessel and not the new find, I’m wondering if the image is the brig Betsy, used as a troop transport. The excavation of Betsy discovered that a carpenter had chiseled a hole in her planking to scuttle her, she was not burned.
