South African big-wave surfer and stand-up paddleboarder Chris Bertish announced this past weekend that he would be making his second attempt at the SUP 24-hour open-ocean distance world record, a title the 2010 Mavericks Big Wave Invitational winner first attempted back in early January.

And while things were looking promising during the first leg of his 24-hour paddle on Tuesday, Feb. 17, the attempt was called off less than halfway through when weather conditions started to deteriorate.

"It started out in blissful conditions, as the ocean does display its beauty before its unpredictability," Bertish wrote on his Facebook page. "[Conditions] turned for the worst eight hours earlier than expected, at 10 p.m."

Bertish cites bumpy seas, strong headwinds, thick fog, and circling sharks as the reasons why he had to be pulled from the water around 10 p.m. He was also suffering from the early stages of hypothermia and had started vomiting.

In December 2013, Bertish set the 12-hour open-ocean distance world record with 130 kilometers. The current record for a 24-hour distance paddle is 157 kilometers; Bertish is aiming to paddle 170 kilometers. His second attempt was in support of Miles for Smiles, an organization that provides corrective surgeries for children with cleft palate deformities.

"Ten hours and 23 minutes can never be underrated; a lot can happen in this time frame," Bertish posted after his second attempt was cut short. "Believe me, I know."

Bertish followed up by announcing the August 2015 release date for his new book, "Stoked," a memoir about his life, travels, and career in big-wave surfing.
