Why This Harbor Matters

At Leinster Bay, a mooring on St. John’s north shore puts two very different outings within the same visit. Waterlemon Cay draws crews with masks and fins, while the walk toward Annaberg gives anyone who would rather stay dry a reason to go ashore. That choice makes the bay a good fit for crews who want more from a stop than a single outing.

There’s a different view of the bay depending on how you spend the day. From the boat, the shoreline connects the beach and the hills above it. In the water, the scale changes to patches of seagrass off the beach and coral around the cay. Give each setting the time it deserves instead of trying to fit the whole bay into one swim.

The walk brings a different part of St. John into focus. At Annaberg, the remains of the sugar works and the quarters used by enslaved people tell the story of the labor behind the island’s sugar industry. That history gives a visit ashore weight of its own.

Bring the provisions and gear you want aboard and decide how much time to give the bay once you know what the crew wants to do. A short visit leaves room for a single outing, while a night on a suitable park mooring lets the shore and water each have their turn.
