Many of the outer cays are privately owned, some supporting their own airstrips. Flying inbound to Abaco are direct commercial flights from Florida and Nassau. Both Treasure Cay and Marsh Harbour being Ports of Entry for Bahamas Customs & Immigration. Marsh Harbour holds the largest community within the islands, just shy of 6000 people. The town supports major food centers, hardware stores and marine supply establishments with yachting the principal source of visitors within the islands. Marinas are many and scattered throughout the Abaco Cays offering provisions, restaurants, fuel & dockage.
These early inhabitants survived in the islands from salvaging wrecked ships and becoming master boat builders, a trade that the Abaco Cays have become famous for, well in demand by boaters from all walks of life today. The boat yards of Man-o-War Cay produce amazing hulls, crafted as no other within the Bahamas. Walking the narrow streets, only wide enough for golf carts, one passes classic wooden hulls on the side of the roads being restored or finished inside the yards as a new product.
