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) - HMS FISGARD II offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The HMS Fisgard II, originally the ironclad battleship Invincible, rests at 46 metres and offers a proper deep wreck dive. We love the sheer scale of it, an 85-metre hull that demands multiple visits to properly appreciate. Dropping down, you feel the history, knowing this vessel was once a formidable warship before its transformation into a training ship and eventual sinking in 1914 while under tow. Visually, it's a spectacle of metal and marine growth. Plumose anemones blanket the structure in a furry white carpet, especially in the darker, less exposed sections. Schools of pout and juvenile pollack dart through the skeletal remains of the deck, and we've often spotted hefty conger eels peering from behind collapsed bulkheads – they love the sheltered nooks here. On a clear day, with decent visibility, the sheer length of the wreck materialises out of the green, a truly impressive sight. This site really suits experienced wreck divers comfortable with depth and colder UK waters. We’d suggest Nitrox for extended bottom time, and definitely a good torch to pick out the details. The current can be brisk, so slack water is your friend here.
