Brigham Barnes, who had lined up on Saturday to enter the ship with a friend, said the young man fell on the south side of the sculpture and, shortly after, Hudson Yards employees set up a small blocking tent view.

“Everyone was very calm,” Mr. Barnes said.

On Sunday, dozens of visitors lined up to enter the sculpture. No areas appeared to be restricted and a security guard was not aware of any additional security measures, but said the guards were being trained to look for possible suicides.

“Our deepest condolences go out to the family of the person who lost his life last night. We have no further comments at this time, ”said Kathleen Corless, spokesperson for Hudson Yards.

The ship, along Manhattan’s West Side Highway, was designed by Thomas Heatherwick and Heatherwick Studio. Visitors are encouraged to climb what the creators call an interactive work of art with nearly 2,500 individual steps and 80 landings that offer breathtaking views of New York City and the Hudson River.

Mr Heatherwick’s office did not respond to requests for comment.

Visitors and reviewers have raised concerns that the design could pose security risks. Audrey Wachs, former associate editor of The Architect’s Newspaper, wrote in a published review in 2016: “When you get on the ship, the railings stay just above waist height to the top of the structure, but when you build high people will jump. “

On Sunday morning, Ms Wachs woke up to Twitter notifications regarding her 2017 exam and news that confirmed her worst prediction. “I feel bad for this person, his family and his friends,” Ms. Wachs said. “This is not a review that you want to be right.”
