Port Nelson Anchorage
The historic harbour of a sleepy Bahamian village where world-class diving meets authentic Out Island hospitality.
Port Nelson is the sole settlement and primary anchorage on Rum Cay, a nine-by-five-mile island that remains one of the Bahamas' best-kept secrets. The harbour curves beneath the village, protected by a long breaking reef to the south that shields vessels from ocean swells while creating some of the clearest underwater visibility in the world.
Despite changes over the years, Rum Cay retains its authentic Out Island character. Fewer than 100 residents call the island home, living a quiet life centered on fishing and the occasional visiting cruiser. The surrounding waters offer exceptional diving and snorkeling, with vivid coral reefs and historic wrecks drawing underwater enthusiasts from around the world.
Approach and Navigation
The anchorage at Port Nelson lies between the settlement's distinctive house with the shiny roof and the dock. Make your way in by eyeball navigation, reading the water carefully as depths transition from deep blue to turquoise shallows. Turn toward the beach if you want to anchor closer to Port Nelson village.
Do not proceed west of Cotton Field Point. Depths in the anchorage area range from 6 to 9 feet, adequate for most cruising vessels. The former marina at Port Nelson has silted up and is now blocked by a substantial sandbar, leaving anchoring as the only option for visiting vessels.
Holding and Protection
The harbour offers a large anchoring area with the curve of Rum Cay to the north and a long protective reef to the south. Holding is in sand and is generally good once your anchor is set. The reef breaks ocean swells effectively, though some cruisers report a persistent roll that can be uncomfortable.
Port Nelson is exposed to south and west winds, which can render the anchorage untenable. In settled conditions with easterly trades, the harbour is comfortable and provides a pleasant base for exploring the island. Monitor forecasts carefully and be prepared to depart if winds shift unfavorably.
What's Ashore and Nearby
Port Nelson village is sleepy and small, but welcoming to visitors. Basic provisions may be available, though selection is extremely limited. The island's historical ruins offer glimpses into Rum Cay's past as a salt-producing and agricultural center. Walk the quiet roads to explore the settlement and meet locals who maintain traditional Bahamian ways of life.
The underwater world is Rum Cay's greatest attraction. Some of the best visibility in the world reveals vivid coral reefs just offshore. Dive sites include historic wrecks and dramatic wall diving along the island's drop-offs. The island's position on the migratory path of pelagic species means encounters with larger marine life are possible.
Cruising Considerations
Rum Cay is remote and services are minimal. The former Sumner Point Marina is no longer operational, so plan to anchor and be self-sufficient. Fuel availability is uncertain, so arrive with full tanks. Fresh water and provisions should be brought from your last supply port.
Despite the limited services, or perhaps because of them, Rum Cay offers an authentic experience that has largely disappeared from more developed Bahamian islands. The combination of exceptional diving, genuine solitude, and friendly locals makes the extra preparation worthwhile.
Getting there
Rum Cay lies approximately 50 nautical miles southeast of Georgetown, Exuma, and 10 nautical miles southwest of Conception Island. Most cruisers approach from Long Island, San Salvador, or Conception Island. The approach to Port Nelson is straightforward in good visibility. The settlement's buildings and the distinctive house with the shiny roof serve as landmarks for locating the anchorage.
