Scuba diving at Bowbelle / Bom Rei Wreck in Madeira

Bowbelle / Bom Rei Wreck

About This Site
The Bowbelle (renamed Bom Rei in Madeira) is the island's deepest and most celebrated named wreck, consistently ranked alongside the Corveta Afonso Cerqueira as a must-do for experienced divers. This 90 m former Thames sand-dredger — infamous in the UK for the 1989 Marchioness disaster on the river — was working as an aggregate carrier off Madeira when it was caught fully laden in heavy weather off Ponta do Sol and sank in 1996, breaking into two sections. It now lies on a sand slope off the south coast, the deck reaching up to around 30 m and the hull settling onto sand near 38 m. The depth, the scale of the hull and the two-part break make it a genuine deep-wreck dive, and decades on the seabed have turned it into a rich artificial reef.

The Bowbelle sits just off Ponta do Sol on Madeira's leeward south coast, with the island's high bulk to the north shielding it from the dominant W-NW-N Atlantic groundswell that pounds the north side of the island — the reason the south coast is the calm, divable side. The exposed window is the open Atlantic to the south, so the S-SSW-SE sector is fully open and it is southerly swell or a sustained southerly wind that builds waves here. Adjacent headlands, including the Ponta do Sol point and lido to the east, partially shadow the E and W sectors, while anything from the northern half of the compass is blocked by land. As a deep wreck it is little bothered by day-to-day chop, but a southerly blow or distant south swell can make the surface and descent line rough enough to call a dive off.
