About South Channel Fort

This man-made island named South Channel Fort was built in the 1880's and houses gun placements, underground tunnels and turrets. It is also the nesting ground for many species of seabird. Both the above-water and underwater environments are worth a visit. Underwater the pylons of the jetty provide a nursery for Old Wife fish.

Dive Site Hazards

Bubble Trapping Under Overhangs — Rock overhangs can trap exhaled bubbles, reducing visibility and causing disorientation.
Reflected Surge Patterns — Surge reflecting off rock faces can create irregular and unpredictable water movement.
Current Funnel Effect — Narrow gaps between rocks can accelerate water flow unexpectedly.

Eddy Pull-Off Zones — Eddies behind structures can pull divers away from the main drift line.

Delayed Surface Pickup — Strong current can exceed surface tracking assumptions, delaying boat pickup.

Vertical Current Shear — Currents may vary by depth, causing vertical separation even when divers stay together.
