"On the south west point of the island the beams of a large vessel were discovered, and as the crew of the Zeewyk, lost in 1728 [sic], reported having seen the wreck of a ship on this part, there is little doubt that the remains were those of the Batavia, Commodore Pelsart, lost in 1627. We in consequence named our temporary anchorage Batavia Road, and the whole group Pelsart Group."
