Arriving yachts make contact over VHF channel 16. The Gobernación Marítima Hanga Roa on Ave. Apina, the building on the coast with the Chilean flag, handles clearance.
About 30 cruising yachts a year visit Easter Island between Galapagos/South America and Pitcairn/Tahiti. Because of Rapa Nui's remoteness, the boats will have been at sea two to four weeks before landfall. As Easter Island is well outside the South Pacific hurricane zone, they usually call January- March, so as to time their arrival in French Polynesia for the beginning of the prime sailing season there.
The southeast tradewinds extend south to Easter Island most reliably December-May, allowing for the easiest entry/exit. The rest of the year, winds are westerly and variable.
Anchorages include Hanga Roa, Vinapu, Hotu Iti, and Anakena/Ovahe, and a watch must be maintained over yachts at anchor at all times as the winds can shift quickly in stormy weather. The anchorages are deep with many rocks to foul the anchor and little sand. Landing can be difficult through the surf. The frequent moves necessitated by changing winds can be quite exhausting, and crews often have only one or two days a week ashore. Luckily the things to see are quite close to these anchorages.
A pilot is required to enter the small boat harbor at Hanga Piko. Entry through the breakers and rocks is possible only in calm weather. Mooring to the concrete wharf here is stern to as at Tahiti (no charge), but there's little space and this is supposed to be done only by boats in need of repairs. The harbor has 2.8 meters of water at low tide. Barges used to unload cargo from oceangoing ships are kept here.
