Monster waves hit Nazaré, Portugal in February 2017 and some of the world's best surfers were there to take them on.

In one dramatic incident, all filmed by a drone, Pedro Scooby Viana from Brazil catches a giant wave but loses control and falls in a dangerous part of Praia do Norte.

Surfer Lucas "Chumbo" Chianca attempts to rescue Pedro on his jetski but things don't go according to plan and Scooby and Chumbo's jetski capsizes and they both get knocked into the churning white water.

Now surfer Everaldo "Pato" Teixeira is forced to try to rescue them both on his jetski and there's no time to lose as they're drifting perilously close to the rocks.

Pato stays cool and picks up Scooby and then a few minutes later returns for Chumbo.

Scooby, Chumbo and Pato survived the incident with no serious injuries.

The wave surfed by Scooby was one of the highlights of the session and has already been entered into the WSL Big Wave Awards.

New unreleased drone footage of Professional Big Wave Surfer from Brazil, Pedro Scooby Viana riding a huge wave in Nazaré - Portugal, followed by a dramatic but yet spectacular rescue operation.

Scooby successfully rode the most critical part of the giant wave but lost control and fell at the end on the dangerous inside zone of Praia do Norte. In order to put Scooby in a safe zone, there was a first jet ski rescue attempt performed by Surfer Lucas "Chumbo" Chianca also from Brazil, but things didn't went well with both Scooby and Chumbo ending up on the rough white water of Nazaré, after the Jet Ski capsized and got crashed by a wave.

There was then a second rescue attempt, this time performed by their Brazilian team mate and veteran Big Wave Surfer Everaldo "Pato" Teixeira, who had the hard task to rescue them both on a much more critical area (they were now very near the rocks of the North Cliff). With decades of experience, Pato maintained his calm, and one by one he successfully rescued first Scooby and few minutes later Chumbo. Luckily the first jetski was pushed to land, ending up flipped down on the sand.

Both Scooby, Chumbo and Pato survived this episode with no serious injuries. The wave surfed by Scooby was considered one of the highlights of the session and is already an entry to the WSL Big Wave Awards.
