Reao High Sea

The Reao High Sea belongs to the eastern Tuamotu world, where scattered coral islands stand amid long Pacific passages. Winds and currents shape travel, while the spacing of land makes provisioning and navigation central to a voyage. Reefs offer resources and possible shelter, but their approaches can be dangerous when seas or currents change. Knowledge of the ocean is therefore essential both to finding a destination and to returning safely from it.

Polynesian navigation connected islands across the wider Pacific, using knowledge of stars, swells, winds and signs of land. In 1823 the French expedition aboard La Coquille sighted Reao and named it Clermont-Tonnerre. An account from the voyage describes islanders signaling with a fire and approaching the ship by canoe.
