Why dive here
With 112+ marine species recorded in the area - including dolphins, dwarf minke whales, humpback whales, ocean sunfish (mola mola) and orcas - UB 63 offers some of Scottish East Coast & Borders's richest wreck diving.
The UB 63 is a deep one, a German U-boat sitting upright in 50 metres, a testament to a January day in 1918 when depth charges from British trawlers Fort George and W.S. Bailey ended its patrol. At 55.5 metres long, it’s a substantial wreck, and the upright position makes for a dramatic profile on the seabed. We often find conger eels tucked into the torpedo tubes, and a surprising number of wrasse dart amongst the superstructure, which still offers decent cover despite the years. This isn't a site for the inexperienced; the depth means careful planning and good gas management are essential, but for technical divers, it’s a genuinely impressive piece of history to explore.
