In 2004 he gained recognition as the owner of 'Best Cribbar Barrel Vision Ever' after he pulled into a giant closeout at the infamous big wave spot in Cornwall.
[7][B] In a 93-day trek, Bertish successfully completed a solo, unassisted and unaided crossing of the Atlantic Ocean on a stand up paddle board, going from Morocco to Antigua.
[12][13][14] His $120,000 craft was designed by Phil Morrison, a naval architect, and resembles a connected row-boat and a stand-up paddle board, called ImpiFish.
[11][16] In addition to gaining the Guinness World Record for being the first person to cross the Atlantic Ocean on a stand-up paddle board, Bertish also set another world record during the attempt by travelling the furthest distance solo, unsupported and unassisted over open ocean in a day of 115.86 kilometres (71.99 mi).
[18] Previously he completed a 3½-day 320-kilometre (200 mi) paddle and a "source to sea" run-paddle-bike descent of the Thames River, with an English Channel SUP bonus crossing.
[19] Unofficially and off the South African coast, he set the world record for 12-hour open ocean paddling, covering almost 130 kilometres (81 mi) aided by "great downwind conditions."
[20] In 2018, South African artist, Michael Lee, painted three large oil paintings to commemorate the transatlantic crossing, Atlantic Solo, featuring Bertish battling a storm at night, with a reference to Hokusai's Great Wave image, Atlantic Soul showing the SUP champion in equilibrium with a calm ocean and various aquatic creatures, and Atlantic Epic, illustrating Bertish's arrival at the Pillars of Hercules in Antigua to complete the epic journey.
