MV Tyrrel Bay - Wrecks — Southwest & St George's Harbour, Grenada
Site Overview
The MV Tyrrel Bay was prepared with real care: stripped, cleaned and set upright on the sand off the edge of Boss Reef inside the Grand Anse Marine Protected Area, so that divers could actually tour her rather than just look at her. Swim from the captain's quarters through the engine room and galley up to the bridge — a legible whole ship in recreation depth, already furred with new coral growth and colonised by the reef's first residents. The deck structure spans roughly 12-27 m, with the bridge and upper runs comfortably inside Open Water limits for a full penetration-free tour. 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. Minutes from Grand Anse beach on the southwest coast — the newest stop on every wreck-tour itinerary. Artificial reefs are judged on what they become, and the Tyrrel Bay is already becoming one of the Caribbean's best. 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 at the bow, tour aft through the open accommodation routes as briefed by the guide, and keep the group moving with lines clear; doorways are wide and the layout reads like a map. Depth management: plan the dive to a maximum of 27 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 from the bridge in stages under the boat with a long safety stop above the wreck's new coral. Newer divers can comfortably dive this site, staying within the range flagged by the guide. 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.”

Safety & Hazards

- Dark interiors; any penetration needs wreck training and lines
- Silt in the lower rooms
- Mooring and boat traffic in the MPA
- Swimming too deep into the engine room recesses past 27 m
Traveler Notes
Who is this for?
The rare 'whole ship you can understand' dive — Open Water divers with good buoyancy can tour most public spaces, and the MPA location makes the marine-life show grow yearly. The 12-27 m range suits divers of most certification levels. Only properly trained wreck divers should consider penetration here; everyone else stays outside the hull. Penetration specialists will find room to plan, but the standing invitation here is a swim-through tour, not an overhead adventure. 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 David'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.
