A flotilla of migrating fish — led by a larger-than-life sturgeon-themed boat designed by renowned artist Greg Corbino — will travel the route of the seasonal migration, north from the Atlantic Ocean into the streams of the Hudson. Orchestrated by Rhiannon Catalyst of Catalyst Culture Labs, the fish flotilla will sail north upriver from New York City to Croton, spreading joy, raising awareness, and turning the waterway into a floating work of art.
The flotilla will begin its voyage from our Welcoming of the Fish at Chelsea Piers in New York City at 10:30 am and make its way upriver, arriving for our Fish Village at the Hudson River Music Festival in Croton-on-Hudson by late afternoon.

The R. Ian Fletcher is a key part of Riverkeeper’s on-the-water patrol program. Named after a passionate scientist and environmental advocate, this vessel patrols the Hudson and its tributaries, documenting pollution. As Riverkeeper’s eyes and ears on the water, it plays a critical role in protecting the health of the river and the communities that depend on it.

Named for Riverkeeper co-founder and pioneering conservationist Robert H. Boyle, the Bob Boyle honors his legacy by continuing the work he began in the 1960s — defending the Hudson from industrial and environmental threats. Equipped for water quality collection and testing, the boat helps enforce environmental laws and ensures the river remains swimmable, fishable, and drinkable for future generations.

The Schooner Apollonia is a modern cargo sailboat reviving the age-old practice of wind-powered shipping on the Hudson River. Launched in 2019 and meticulously restored from a 1946 steel-hulled schooner, the Apollonia is a floating symbol of sustainable commerce, delivering local goods like malt, coffee, and maple syrup using only renewable energy.

Built in 1931, the John J. Harvey is one of New York Harbor’s most storied vessels. Once among the most powerful fireboats in the world, it served the New York City Fire Department for decades and was brought out of retirement to help fight fires and evacuate people on 9/11. Today, the restored Harvey offers public educational trips and celebrates maritime heritage as a floating museum.
