The Andamans are the exposed tips of a submarine mountain chain, and the 2004 earthquake lifted or dropped parts of the archipelago by more than a metre, changing the reef line permanently. Access is controlled, parts of the group are closed to protect the Jarawa and Sentinelese peoples. Anchorage: Anchor off Havelock's Vijaynagar or Govind Nagar beaches; the Andamans are a restricted cruising ground and require clearance. Hazards: Open-sea pinnacles with current and no surface reference; strict deco discipline, and the nearest chamber is in Port Blair. Más
