South Korea's coastguard said Tuesday it had arrested a Chinese national who tried to enter the country after travelling by jet ski from China -- a journey of more than 300 kilometres (186 miles).

Wearing a life vest and helmet, the man crossed the Yellow Sea on a 1800-cc jet ski from Shandong province, using binoculars and a compass to navigate and towing five barrels of fuel.

"He refilled the petrol on the ride and dumped the empty barrels into the sea," the coastguard said in a press release.

That’s actually pretty badass.
