Why dive here
With 176+ marine species recorded in the area - including blue sharks, dolphins, dwarf minke whales, humpback whales and ocean sunfish (mola mola) - BRESTOIS offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The *Brestois* sits in about 37 metres of water off Plymouth, a substantial iron steamship that went down after a collision in 1918. For us, this wreck is one of the standout dives in the area, a proper penetration dive if you know what you’re doing and have the right training. You’ll drop down onto the bow, often with impressive visibility, and find yourself looking into the cavernous holds. We love finning through the open sections, seeing light filter down, illuminating massive conger eels peering out from gaps in the plates. Our favourite part is the engine room, surprisingly intact, where you can still make out machinery wrapped in anemones. Keep an eye out for dogfish resting in the sand nearby, and big ballan wrasse patrolling the perimeter. The *Brestois* really gives you a sense of its history; you can almost feel the chill of that March morning it went down. It’s definitely one for experienced cold water wreck divers who appreciate a good, honest dive with plenty to explore, especially those who enjoy a bit of overhead environment.

The SS Brestois was a French-owned, iron-hulled steamship built in 1897. Her career came to a violent end during the final year of World War I, a period when German U-boats were relentlessly targeting Allied shipping in the English Channel. On March 7, 1918, the Brestois was on a voyage in ballast from Cherbourg, France, to Cardiff, Wales, when she sailed into the periscope sights of the German submarine UB-55.
Without warning, the U-boat launched a torpedo that struck the Brestois, sealing her fate. The explosion was catastrophic, and the ship sank quickly, tragically taking 18 of her crew members with her to the seabed. She became another statistic in the brutal war at sea, a civilian vessel lost to a military conflict.
Today, the wreck of the Brestois lies at a depth of 37 meters. It's a dive for more experienced enthusiasts, offering a poignant glimpse into the past. The wreck is broken but key features, including her single boiler and compound expansion engine, are still clearly identifiable. As you explore the scattered remains, now colonized by anemones and patrolled by fish, it's impossible not to reflect on the sudden and violent end this vessel and her crew met over a century ago.
