The catamaran slips from Rosslyn Bay and the coastline thins into open water. Salt spray picks at your cheeks, the sun tracks high, and the boomnet yawns behind the boat like a mechanical tide pool daring you to climb in. Inland, the island rises as low granite knolls and white sand; offshore, coral gardens ripple beneath a clear, shallow lagoon.
