    Hema One, Grenada’s newest big wreck, went down in 2011. We think it’s already developed a character, quite distinct from the other Grenadian wrecks. This 70-metre cargo vessel lies on its starboard side at 30 metres, pointing across the usual current, which means you’ll often get a drift dive along its length. Inside the collapsed cargo hold, it’s all about the crustaceans – lobsters are everywhere, and we’ve seen nurse sharks tucked away in there too. Our favourite part is often just hanging out above the deck. We've regularly seen schools of barracuda, so thick they almost obscure the sun, and those graceful eagle rays often glide by. Turtles are pretty common, usually resting near the stern. The visibility averages around 12 metres, which is decent enough to appreciate the scale of the ship. We find it suits divers who enjoy a deeper wreck with a good chance of encountering larger pelagics in a relatively short time. The currents can be a bit frisky, so it's not one for the absolute beginners.

    Safety Notes

    Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.
