Low tide wreck

A small boat, wrecked on Ettrick Bay. Wooden hull, with some edges just visible. Iron or steel machinery of some kind in the middle of the hull. I have no idea how long she's been there. The 'Isabella' was a famous-ish recent, but she is gone now, apparently. This one only appears at a very low tide, like this day. I wonder what she was, how she ended up there, why she wasn't refloated, what lives were wrapped around her. But now just some low, low tide traces...
