HMS SESAME (PROBABLY)
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 SESAME (PROBABLY) offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The HMS Sesame, or what we strongly suspect is the Sesame, rests upright in about 20 metres of water off the coast of Cornwall. It’s a proper dive, feeling its history as you descend into the often-murky green. We love the way the wreck has settled, largely intact, offering easy penetration for those with the right training and a good guide. You'll find schools of pollack hanging in the superstructure, darting into the shadows as you approach. Keep an eye out for conger eels too, peering from the deeper recesses. While the visibility can be challenging, typically around 5-10 metres on an average day, we think that only adds to the atmosphere, making those moments when a feature emerges from the gloom all the more dramatic. Our favourite part is exploring the bridge area, though we’d suggest going at slack water, as currents here can pick up. It's a dive for those who appreciate a good wreck with a story, not just perfect visibility.
