Boat-access shark reef with strong current
Boat-access shark reef with strong current
A hand-shaped reef near the Mozambique Channel with sandy pockets, fast water, and a profile that rewards experienced teams. The site is known for shark encounters, garden eels, bigeye trevally, and snapper, so the dive is more about current management and open-water awareness than leisurely reef cruising. Good timing matters more than trying to cover the whole structure.
