A group of Dutch high school students with little sailing experiencecompleted a five-week trip across the Atlantic Ocean on Sunday.The group said they returned home by boat instead of by airplane because of coronavirus travel restrictions.The students, ages 14 to 17, were joined by 12 experienced crew members and three teachers.They had been taking part in an educational cruise of the Caribbeanwhen the coronavirus outbreak forced them to greatly change the way they returned home.The change in plans taught 17-year-old Floor Hurkmans an important life lesson."Being flexible, because everything is changing all the time," she said."The arrival time changed like 100 times. Being flexible is really important."Instead of flying back home from Cuba as they had planned,the crew members and students gathered supplies and warm clothes.Then, they set sail for the Dutch port city of Harlingen, 7,000 kilometers away.Their boat, the Wylde Swan, arrived at Harlingen late Sunday morning.Observers gathered at a sea wall to watch the arrival.As they arrived, the students hung up a self-made sign on the boat that read "Bucket List."It showed they had completed activities that included crossing the Atlantic Ocean,mid-ocean swimming and surviving the Bermuda Triangle.The Bermuda Triangle is an area in the Atlanticwhere some people claim ships and planes have mysteriously disappeared.The students' family members were waiting for them at the port.Parents drove their cars next to the boat one by one to follow social distancing rules.On the ship, it was impossible to follow any kind of social distancing, Hurkmans noted."Here you have to be social all the time to everyone because you're sleeping with them,you're eating with them you're just doing everything with them so you can't really just relax," she said.Her mother, Renee Scholtemeijer, said she expects her daughter to miss life on the open seaonce she understands the coronavirus containment measures in the Netherlands."I think that after two days she'll want to go back on the boat,because life is very boring back at home," the mother said."There's nothing to do, she can't visit friends, so it's very boring."Masterskip, the company that organized the boat trip,runs five educational cruises for about 150 students each year.Crossing the Atlantic is nothing new for the Wylde Swan, which has made the trip about 20 times.The company's director, Christophe Meijer, said the students were examinedfor signs of the coronavirus in March to make sure nobody was infected.He said he was pleased the students had adapted to life on the boatand had kept up their education on the long trip."They are actually far ahead now of their Dutch school colleagues," Meijer said."They have made us very proud."
