The barrier cays act as a natural shield, creating calmer waters that are particularly attractive for:
- Sailing

This protected environment has historically supported transportation, commerce, fishing, and community development throughout Abaco.
Many settlements originally depended on boats as their primary means of communication and transportation, reinforcing the maritime identity that remains visible today.
