The catamaran slips out of Cairns early, sails filling as the coastline slips astern and the reef reads like a crowd of islands on the horizon. Salt spray tugs at your sleeves and the deck hums with the low conversation of divers and snorkelers; by midmorning you’re anchored off Michaelmas Cay — a white sand spit ringed by shallow coral gardens and a chorus of seabirds.
