Hammerhead Point (Rasdhoo Madivaru)

This is the Maldives' classic dawn gamble, run from Rasdhoo, the small satellite atoll on Ari's northeastern shoulder. Divers roll in before sunrise and hang at 25 to 30 meters in open blue, watching down-slope for the silhouettes of scalloped hammerheads rising from deep water where they spend the day. Some mornings deliver a slow parade; plenty deliver nothing but gray reef sharks and eagle rays on the wall as consolation, and honest guides say the odds have thinned compared with decades past. The dive itself — dark water, no reference, buddy discipline — is a skill test worth the alarm clock either way.

Khoảnh khắc bạn đến vì nó: Dawn blue-water hangs for scalloped hammerheads; wall traffic on the way home

Địa hình: Steep outer wall falling from a channel corner into deep open water

Dòng chảy: Pre-dawn blue-water descent off the corner of Rasdhoo Atoll's channel; flow can push divers off the drop quickly.

Nguy hiểm cần lưu ý: Deep blue-water descents in darkness, no visual reference, and current off the corner.

Bảo tồn: Sightings are wild and unbaited; nothing is done to attract the sharks.

Nitrox: Đáng dùng ở đây — các hồ sơ nằm trong khoảng độ sâu mà nitrox có thể kéo dài thời gian không dừng một cách thực sự có ý nghĩa (khi đã được đào tạo sử dụng).
