one of the most famous is the steamer 'buenos aires,' which ran aground on the island in 1890.

the remains of this and other ships still rest on the seafloor around rasa, and for this reason it is a very popular diving spot.

though the waters around the island are open to fishing, kayaking or the aforementioned diving, the brazilian navy maintains a garrison on ilha rasa, and disembarking at the island is only possible through the acquisition of permission from the proper authorities.
