HMS Basilisk
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 Basilisk offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The HMS Basilisk, what a brute of a wreck. This B-class destroyer met its end in 1930, but it lives on as a spectacular dive in Cornish waters. We love how it's broken up, giving you distinct sections to explore. You'll drop down onto the bow, often with pollock darting through the superstructure, then follow the debris field back to the stern. Visibility can be a typical UK lottery, but when it's good, you can make out the scale of this warship. Our favourite part is poking around the engine room, if conditions allow penetration. The metalwork here is encrusted with dead man's fingers and anemones. Look for conger eels peering from every dark recess, and we've often seen spider crabs scuttling across the deck plates. This isn't a dive for the faint of heart; strong currents can sweep through, so pick your slack water window carefully. It’s definitely one for experienced wreck divers who appreciate the history and the sheer amount of life a century underwater can create.
Safety Notes
Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.
