Atalaia Diving Center
SSI/PADI Dive Resort at Caniço de Baixo, Madeira, running a six-site house reef the centre calls the island's largest, since 1988.
Also known as: Afonso Cerqueira wreck, Corveta Afonso Cerqueira (F488), F488, NRP Afonso Cerqueira, the Afonso wreck
A Portuguese Navy corvette scuttled off Cabo Girão, Madeira in 2018: a penetrable wreck spanning 12 to 33 metres, reached by boat from Funchal.
Last updated September 2026
Boats from Funchal and Caniço de Baixo drop divers onto an intact 85-metre hull resting upright on sand off Cabo Girão, with named points running from the 12-15 metre deck down to the hull past 30 metres. One diver who explored it end to end describes full, easy penetration from stern to bow through the corridors; the confirmed interior route runs through the engine room, the bridge and the crew quarters, and divers follow an operator's guide through it. One account breaks the structure into levels: the deck near 15 metres, the bridge around 22, the engine room and former cafeteria between 25 and 30, and the hull itself on the sand close to the deepest point. Groupers move along the plating, scorpionfish sit tucked into the ironwork, and barracuda, trumpetfish and grey triggerfish work the open water around the superstructure.
Madeira has no coral reefs, and its named sites sit mostly on volcanic terrain the ocean shaped on its own. The Corveta Afonso Cerqueira breaks that pattern: a large naval vessel deliberately prepared and sunk to be dived, and every operator running trips here treats it as the flagship. It hosted the 2022 European Open Championship of underwater photography, and one diver who spent most of a Madeira trip on the island's reefs still singled out the wreck as the standout two dives of the week.
She was built as the NRP Afonso Cerqueira (F488), a Baptista de Andrade-class corvette laid down by Bazán in Cartagena, Spain, and commissioned into the Portuguese Navy on 28 June 1975.1 Over the following four decades she deployed to Timor during the 1975-76 conflict, took part in the December 1975 bombardment of Dili, completed a circumnavigation by way of the Pacific and the Panama Canal, and represented Portugal at the 1976 United States Bicentennial celebrations. She was decommissioned on 11 March 2015.1
Three years later, between 14:30 and 16:00 on 4 September 2018, she was deliberately scuttled south of Cabo Girão to create an artificial reef, in what is now managed as the Parque Natural Marinho do Cabo Girão.2 Portuguese Navy divers filmed the sinking and captured its first underwater images; the stated purpose was to grow biodiversity and support underwater tourism on this stretch of coast.
Azul Diving Center runs trips from Funchal, and Manta Diving Madeira, based in Caniço de Baixo, puts the boat ride at around 30 minutes. A third operator, XPoint Madeira, based at the Pestana Carlton Hotel in Funchal, calls this its signature wreck dive; its site was previously reached under the name Madeira Divepoint, and whether that reflects a rebrand or two separate businesses is not confirmed.
Operators ask for Advanced Open Water to dive the wreck, and one account also names a wreck specialty certification alongside a guide for the interior sections. That bar sits below what the deepest reported points actually need: 33 metres runs past the 30-metre ceiling most Advanced Open Water training covers. Let your guide's briefing set how deep you go on the lower levels and any penetration; do not use the certification card alone as your limit.
Interior penetration is only for divers with a wreck-trained guide and the right certification; the corridors are not a solo route. The site falls under a separate marine park from the Garajau reserve that covers most of Madeira's other sites, and whether a comparable entry fee applies here remains an open question; ask your operator for the current position when you book.
What makes this dive site stand out.
Confirmed interior route through the engine room, bridge and crew quarters
Sunk 4 September 2018 to form an artificial reef off Cabo Girão
Deck starts around 12-15m, down through the bridge and engine room to the hull on sand past 30m
Regular boat trips from Funchal and Caniço de Baixo
32.6495°N, 16.9880°W
Operators ask for Advanced Open Water. The wreck's deepest reported points reach 33m, past the 30m ceiling AOW is built around, so treat the lower levels and any penetration as guided diving, not an independent depth limit.
Summary
The deck and bridge suit a comfortable Advanced diver; the engine room and crew quarters are for divers with a wreck specialty and a guide.

Madeira, off Cabo Girão on the south coast. It is sometimes confused online with Porto Santo's own former Navy corvette, the Corveta General Pereira d'Eça, known locally as the Cordeca, an 85m vessel sunk near Porto Santo in 2016. The two are separate wrecks in two different island groups.
Advanced Open Water is the certification operators state as their minimum, but its standard training covers depth to 30m. The wreck's deepest reported points reach 33m, so the lower levels and any interior penetration follow a guide's briefing, not a depth ceiling read off a certification card.
The Portuguese Navy's own museum record and an operator's independent account agree that she served from 28 June 1975 to 11 March 2015, close to 40 years. A wider Madeira diving guide instead gives 43 years of service; with two independent sources naming the exact dates and both adding up to about 40, that is the better-supported figure here.
The confirmed interior route runs through the engine room, the bridge and the crew quarters, and one diver reports full penetration from stern to bow. Go inside only with an operator's wreck-trained guide and the right certification.
Groupers, scorpionfish, barracuda, trumpetfish and grey triggerfish work the hull and superstructure, and the eight-year-old reef is still colonising with algae and sponges. Divers who have dived Madeira's reefs on the same trip still call the wreck the standout two dives, drawn by the structure itself; the wildlife is a welcome extra.
One account mentions a lucky, occasional dolphin sighting, but it is not a reliable encounter here: don't plan the dive around seeing one.
