GRETAFIELD (AFTER PART) - Scapa Flow, Orkney
The *Gretafield* (After Part) sits shallow, right on the edge of Scapa Flow, a stern section from a tanker that met a U-boat in 1940. We love how accessible this part of the wreck is, especially on a sunny day when the light spills in. You’ll fin down to around 10 meters, spotting the huge triple-expansion engine almost immediately, standing proud amidst the skeletal remains of the hull. It’s a proper engine room dive, with gauges and levers still in place, inviting exploration. Look for the enormous prop shaft disappearing into the stern tube, and imagine the sheer power it once commanded. We often find conger eels tucked into the dark recesses, and the wreck itself is plastered in plumose anemones, their white tentacles swaying in the gentle surge. This site is fantastic for photographers or anyone wanting a relaxed dive with a tangible piece of history; it’s not about grand scale, but about the intricate details.
