Dozens of people jumped and cheered as Dekker waved, wept and then walked across the dock accompanied by her mother, father, sister and grandparents, who had greeted her at sea earlier.
Dekker, 16, arrived in St. Maarten after struggling against high seas and heavy winds on a final, 41-day leg from Cape Town, South Africa.
“There were moments where I was like, ‘What the hell am I doing out here?,’ but I never wanted to stop,” she said. “It’s a dream, and I wanted to do it.”
Dekker claims she is the youngest sailor to complete a round-the-world voyage, but Guinness World Records and the World Sailing Speed Record Council did not verify the claim, saying they no longer recognize records for youngest sailors to discourage dangerous attempts.
Dutch authorities tried to block Dekker’s trip, arguing she was too young to risk her life, while school officials complained she should be in a classroom.
Dekker said she was born to parents living on a boat near the coast of New Zealand and said she first sailed solo at 6 years old. At 10, she said, she began dreaming about crossing the globe. She celebrated her 16th birthday during the trip, eating doughnuts for breakfast after spending time at port with her father and friends the night before in Darwin, Australia.
The teenager covered more than 27,000 nautical miles on a trip with stops that sound like a skim through a travel magazine: the Canary Islands, Panama, the Galapagos Islands, Tonga, Fiji, Bora Bora, Australia, South Africa and now, St. Maarten, from which she set out on Jan. 20, 2011.
Unlike other young sailors who recently crossed the globe, Dekker repeatedly anchored at ports along the way to sleep, study and repair her 38-foot (11.5-meter) sailboat.
During her trip, she went surfing, scuba diving, cliff diving and discovered a new hobby: playing the flute, which she said in her weblog was easier to play than a guitar in bad weather.
Dekker had said she planned to move to New Zealand after her voyage, but she said Saturday that she wants to finish school first.
