The rock had been variously reported in no fewer than six widely differing positions (marked A–F). In September 1838 H.M. vessels Etna and Raven were tasked with examining these sites, plotting their soundings and tracks across the suspected area. No permanent hazard was found, and the feature was ultimately dismissed as a phantom reef — likely arising from misreported breakers, floating or submerged debris, optical effects, or positional error — and later removed from Admiralty charts.\u003c\/em\u003e\u003c\/p\u003e","brand":"Antiquemapsandprints.com","offers":[{"title":"Default Title","offer_id":52504281514331,"sku":"P-6-111261","price":280.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0923\/9583\/1643\/files\/P-6-111261a.jpg?v=1772563624","url":"https:\/\/www.antiquemapsandprints.com\/fr\/products\/cape-verde-islands-h-m-ships-search-for-the-phantom-bonetta-rock-1839-map-p-6-111261","provider":"Antiquemapsandprints.com","version":"1.0","type":"link"}
