Why dive here
With 112+ marine species recorded in the area - including dolphins, dwarf minke whales, humpback whales, ocean sunfish (mola mola) and orcas - HMS OTHONNA offers some of Scottish East Coast & Borders's richest wreck diving.
The HMS Othonna isn't your average trawler wreck. Down at 42 metres, she’s a proper dive, certainly not for the faint-hearted or those new to deep British waters. We love how intact she remains, lying upright on the seabed, a real snapshot of a bygone era. Her size, 33.8 metres, means you can properly explore the deck, peer into the holds, and even get a good look at that single boiler and triple expansion engine. You'll find the Othonna colonised by a good variety of local marine life – plenty of squat lobsters tucked into every nook and cranny, and often a decent sized conger eel making its home in the deeper sections. The visibility here can be temperamental, as is often the case on the East Coast, but when it’s good, the light filtering down through the kelp-draped superstructure is something special. We’d suggest timing your dive for slack water to truly appreciate her undisturbed. This is a site for experienced wreck divers who appreciate history and don't mind the chill of the North Sea.
