A sunk vessel named 堡壘號 rests at 36 m in Badai Bay and now serves as an artificial reef. It is a boat dive only, rated advanced, with a strong current across the wreck. Large sea fans, coral and schools of fish gather deeper inside the hull.

Also known as 八代灣沈船, 八代灣沉船, 堡壘號.

The dive

The dive is made from a boat, a short run of about five minutes out of Badai Bay. The vessel 堡壘號 lies on the bottom at 36 m, and the strong current across it is part of why the dive is rated advanced.

Moving into the deeper parts of the vessel, divers find several large sea fans and corals, with schools of fish gathering around them. Conditions decide how much of this shows, and a clear look at the wreck takes some luck on top of technique.
