Tutuba Point

Tutuba Point is where Santo remembers it has ocean diving as well as wrecks. The island's tip drops through coral terraces into channel-scoured blue, and on a running tide the point works like a tollbooth: trevally and barracuda queuing up-current, whitetip reef sharks patrolling the terraces, eagle rays planing past the wall, turtles commuting between grazing spots. The coral here is healthier than the harbor sites, fans and whips angling into the flow. It is the standard prescription for divers with the Coolidge ringing in their ears — a reminder that Vanuatu's reefs would justify the trip even if the great ship had made port safely.

その瞬間のために: Drift diving on the channel tide; eagle rays and reef sharks off the point; the trip's best straight reef scenery.

地形: Coral point and wall terrain where the Segond Channel meets open water

流れ（カレント）: The point catches channel flow; the fish arrive with it.

エントリー: Boat run across the Segond Channel to Tutuba Island; dived on the tide as a drift along the point.

危険生物・リスク: Current at the point; boat traffic in the Segond Channel; exposure to chop on the crossing.

保全: Reef custom applies on Tutuba — operators arrange access, and the point's coral deserves the same care as the wrecks' artifacts.
