Why dive here
With 140+ marine species recorded in the area - including blue whales, dolphins, dwarf minke whales, humpback whales and ocean sunfish (mola mola) - ST GERALDINE offers some of Scapa Flow, Orkney's richest wreck diving. Water ranges 8-14°C, warmest July, August, September.
The ST GERALDINE, a fishing vessel about 14 metres long, sits at a depth of 56 metres in Scapa Flow. It’s not the biggest wreck in the Flow, we’ll grant you that, but it has a charm all its own. Being a smaller boat, it feels more intimate, like you’re peering into a lost day’s work rather than a grand naval history. You can still make out the outline of the wheelhouse and the general shape of a stern trawler, with nets and rigging collapsing around it. What really makes the ST GERALDINE worth the deep dive is the life that’s taken hold – we’ve seen some decent-sized conger eels making homes in the hull, and the deck plates are often covered in anemones and small crabs. It’s a good choice for those keen on deeper technical dives who want to explore something a little different from the more famous Scapa Flow behemoths.
