Rasgefanno was once the island's harbour, and it is now dived as a wall that drops steeply from 5 to 20 metres before easing into a slope. Batfish and fusiliers school along the face, lobsters shelter in the rock, and thresher sharks cruise a cleaning station at around 35 metres.

The dive
You drop onto the top of the wall in about 5 metres and follow it down. The face is steep and continuous to roughly 20 metres, with anemones on the rock and schooling batfish and fusiliers along it. Lobsters are part of the site's species list too, so it is worth looking into the cracks and under the ledges rather than only out into the blue.
Below 20 metres the wall gives out into a gentle slope, and that slope carries a cleaning station at around 35 metres where thresher sharks are seen. Fuvahmulah has no atoll around it to shelter behind, so the deep part of the dive is short and the group stays tight on the structure before working back up onto the wall to finish shallow among the reef fish.
Anemones, batfish and fusiliers fill the shallow half of the dive between shark passes, and they are what the site offers when nothing shows deeper. There is no reef flat to potter on at the end, so the ascent and safety stop are done off the wall in open water, with the boat picking the group up wherever the drift leaves it.

Season follows Fuvahmulah: Tiger sharks are resident year-round; the dry NE monsoon (Dec-Apr) gives the calmest seas, while the Oct-Nov transition brings choppier open-water conditions.
Know before you go
- The cleaning station sits at around 35 m, which leaves very little no-decompression time; agree a turn depth and gas plan before descending.
- There is no atoll around Fuvahmulah, so open-ocean current can run along the wall — stay on the structure and surface where the drift leaves you for pickup.
