Memoria Hydrografica Das Ilhas De Cabo Verdepara Servir De Instrucção a Carta Das Mesmas Ilhas, Publicada Em O Anno De 1790

A scientific publication written in the early 19th century. The book serves as a detailed account of the hydrography of the Cape Verde Islands, aiming to provide a more accurate navigation guide by correcting previous nautical charts and offering practical insights for sailors. In this work, Cabral critiques the existing nautical charts, particularly those of Mr. d'Aprés, asserting that his own findings provide a more accurate representation of the islands' geography and navigational challenges. He emphasizes the importance of precise measurements and firsthand experiences in mapping coastal features, ports, and safe anchorage areas. Throughout the text, Cabral provides extensive descriptions of the islands, discussing their shape, size, and navigational hazards while advocating for the acceptance of his chart among sailors and navigators who frequently navigate these waters. His commitment to accuracy stems from both patriotism and a deep understanding of the maritime conditions affecting the region.
