A British teenager has become the youngest person to sail around the world without assistance.
Seventeen-year-old Mike Perham completed his 28,000-mile trip in nine months. He crossed the finish line today in Cornwall, England.
The Guinness Book of World Records says pending some verification, Perham would be certified as the "youngest sailor to circumnavigate the globe solo and unsupported."
Guinness had originally said that Perham had been accompanied by his father in a boat following behind him, but a spokeswoman says that was a mistake.
He did require some assistance, though. The trip was marred by autopilot failures, rudder problems and brutal weather which repeatedly forced him to stop for repairs.
Perham is a few months younger than Zac Sunderland, a 17-year-old from Thousand Oaks, Calif., who completed a solo trip in July. His took 13 months.
Perham is now sailing to Portsmouth with his father for a celebration on Saturday.
