She’s seas-ing the moment. 

An Olympic sailor navigated her way though the notoriously filthy and “shocking” shores of the Gowanus Canal Wednesday — just days before she hoists anchor on her bid to defend her New York SailGP championship.

Spain’s Nicole van der Velden and dozens of other athletes from across the globe gathered at the toxic Brooklyn waterway’s banks as part of an environmental clean up event before this weekend’s annual yachting competition on the Hudson River.

“We do a sport that’s really connected with nature and in nature. Cleaning and being able to contribute and give back in all the places we go is something super unique and super special,” said van der Velden, who sailed in the 2016 Summer Olympics.

“What motivates me is to see people who live and fight to make our world and the canal a better place and make it a healthier environment for everyone.”

The SailGP athletes conduct an oceanic clean-up event at each of the 13 countries they race in as part of the annual Grand Prix to give back to the communities where they race their high-tech F50 catamarans.

The race involves crews of six who ride the waves at speeds up to 60 mph and navigate the different conditions of each city — last year, Van der Velden won the Big Apple leg of the Grand Prix by artfully dodging the Hudson’s currents and cityscape-crafted waves.

Their volunteer missions have ranged from picking up litter on the shores of Rio de Janeiro to restoring seahorse habitats in southern Italy, and have even crafted artificial reefs with the Billion Oyster Project on Governor’s Island.

The Wednesday trip to perform maintenance work on the Gowanus Canal’s public rain gardens and install protective plants on the shores was the athletes’ first visit to Brooklyn — and was “shocking” for the cosmopolitan group. 

“It’s certainly quite shocking in parts of it: the state that the canals got to, the raw sewage outlets and stuff like that,” said Neil Hunter, an athlete repping Great Britain.

“But it sounds like the [Gowanus Canal Conservancy] is doing an amazing job to try and make the situation better around here. For us, the water is our playground and it’s very important for it to be as clean as possible … It’s amazing to have an impact in the places that we go and try and help them become better.”

SailGP chose the Gowanus Canal this year because of its proximity to their training center at the Brooklyn cruise ship terminal, and it offered a spotlight on the progress the GCC has made in the superfund site over the past decade.

The SailGP athletes will take to the nearby waters of the Hudson River this weekend for the sixth annual competition.

Van der Velden — a Europe Glamour Magazine cover girl — and her team cinched the win last year in the Big Apple leg, though the Emirates Great Britain team went on to win the entire Grand Prix. 

“It’s nice to be able to show those two sides — that you can be strong and get your hands dirty and all of that stuff, but at the same time, you can also be a woman and feminine and want to look good!” Van der Velden said.
