This dive site, known as Cabnav, is situated within the active Cabnav shipyards in Cabo Verde. It is primarily recognized as a unique muck diving location, particularly favored by enthusiasts of macro photography and night diving. The site benefits from its confined nature and protection offered by the pier and docked ships, ensuring tranquil diving conditions. Divers typically navigate along the pier structure, exploring the diverse substrate for hidden marine life. Its shallow depths and sheltered environment also make it an excellent location for dive courses and introductory experiences.
The main attractions at Cabnav are its abundant small and unusual marine creatures. Divers can frequently spot various species of frogfish, conger eels, rays, and trumpetfish. Lobsters are also common, often found tucked into crevices. Additionally, small schools of fish can be observed congregating near the pier and submerged structures, adding to the site's biodiversity.
The best time to visit Cabnav is often during the night, as it is specifically highlighted as an excellent spot for night diving, where many of its unique inhabitants become more active. Its calm and confined characteristics make it ideal for beginners and those undergoing dive training. Freedivers can also enjoy the shallow depths and rich macro life. Divers should be mindful of potential boat traffic associated with an active shipyard, though the diving area itself is protected.
