Campeonato Brasileiro e Copa Brasil de Águas Abertas

The waters off Praia de Cabeçudas are defined by the convergence of the Atlantic and the dynamic mouth of the Itajaí-Açu River. Swimming here means navigating a shifting environment where, depending on the tide and river flow, you might encounter a brisk, refreshing current that demands constant tactical awareness. The seabed is a repository of regional history, most notably the steamboat Pallas. Sunk in 1893 during the intense Brazilian Naval Revolts while attempting to supply meat to protesters, this wreck was rediscovered in 2017 beneath layers of port silt and now acts as a silent, submerged landmark that shapes the modern maritime geography of the area.

Landmarks and race logistics

As you sight your line, two prominent features dominate the horizon. To the north stands the Cabeçudas Lighthouse, a guiding point that provides a clear vantage of the urban coastline. Looking toward the rocks, you will spot the 6-meter-tall Bico do Papagaio (Parrot's Beak), a natural stone formation that serves as an unmistakable turn-marker for many swimmers. The region's connection to the water runs deep, stretching back to the indigenous Carijós people who inhabited these shores before the 16th-century arrival of Portuguese and Spanish colonizers, eventually falling victim to enslavement on local sugar cane plantations. Today, the city is better known as an international hub for nautical sports, having served as a recurring stopover for The Ocean Race since 2011.

Organized by the Confederação Brasileira de Desportos Aquáticos, the event typically takes place in March, offering distances ranging from 1,500m to 10,000m. The schedule often includes the high-intensity 2x2x750m mixed relay, a format that has gained popularity as a qualifier for regional and national selections. While the logistical complexity of managing a busy working port requires strict adherence to start times and safety protocols provided by the organizing committee, the race remains a premier destination for those looking to test their speed in a setting that balances industrial scale with open-sea challenge. The environmental integrity of the surrounding river system is guarded by the nearby 1,899-hectare Canela Preta Biological Reserve, ensuring that the water remains a protected, if challenging, arena.
