Hema - Wrecks — Southwest & St George's Harbour, Grenada
Site Overview
The Hema sank in 1980 and has spent four decades becoming a reef: her shallow end is a cauliflower of hard coral at 12 m while the cargo holds and stern drop toward 30 m, giving two very different dives on one hull. The contrast is the draw — batfish and angelfish pose in the coral shallows at the bow, while the deep, dark holds shelter groupers and veteran spiny lobster in the silted rooms. Work the bow at 12-18 m and let the line run down the superstructure to 30 m for the advanced contingent; the mid-hull crossover is the best air-sharing compromise. The site sits in Wrecks — Southwest & St George's Harbour, one of Grenada's core dive areas, with water at 27-29 °C and typical visibility of 15-25 m. Lies inside the St George's harbour approach, minutes from the waterfront — a rain-day saviour when the open coast is blown out. No plaque, no legend, just a well-grown old wreck doing quiet duty as one of the harbour's best reefs. Trade winds blow almost constant over the Caribbean, and it is their lulls and builds that set the daily diving schedule around Grenada. Water temperature stays in the high twenties year-round and the island sits outside the main hurricane belt, so the dive boats run twelve months a year.
Dive Briefing
“Enter over the bow reef and descend gradually along the wreck spine so each diver can stop at their comfort depth; the deep group loops the stern holds while the shallow group finishes the coral garden. Depth management: plan the dive to a maximum of 30 metres and turn early. The sheltered Caribbean side is usually glassy, while the Atlantic-facing south coast runs with the trade-wind current that makes its drift dives so special. Ascend along the superstructure with a long safety stop over the bow coral. This is an advanced-profile dive; newer divers should stay on the sheltered route and let the guide handle the deep line. Several of Grenada's best waters are protected - the Grand Anse Marine Protected Area, the south-coast preserves and Carriacou's Sandy Island/Oyster Bed MPA all use mooring buoys and small user fees to keep anchors off the coral. Local operators hold the final say on which sites run each day, because a shift in wind or swell can change conditions between two bays.”

Traveler Notes
Who is this for?
Mixed groups love the Hema because one boat, one anchor covers a beginner-friendly coral dive and a genuine 30 m wreck dive at once. The 12-30 m range suits experienced divers comfortable beyond 18 m and in moving water. Only properly trained wreck divers should consider penetration here; everyone else stays outside the hull. Advanced divers use her as a deep-skills playground between the Bianca C runs. The crevices, wreck rooms and sculpture plinths hold the usual Caribbean small life - damsels, blennies, shrimps and the occasional rare frogfish or black seahorse. Night dives on the shallow reefs and harbour wrecks turn up a completely different community of hunters.
For Non-Divers
St. George's is easy to enjoy without a cylinder, and most operators run snorkel trips on the same bays. Several of Grenada's best waters are protected - the Grand Anse Marine Protected Area, the south-coast preserves and Carriacou's Sandy Island/Oyster Bed MPA all use mooring buoys and small user fees to keep anchors off the coral.
