One15 Marina

ONE°15 Brooklyn Marina, New York City’s first new marina in 50 years, offers unparalleled water access to New Yorkers and boating enthusiasts from around the globe.

Located just south of the Brooklyn Bridge in Brooklyn Heights, between Piers 4 & 5, with sweeping views of Lower Manhattan, the Marina features a Sailing Club and School, seasonal docking facilities and an exceptional community program. With the calmest waters in the New York Harbor thanks to its advanced technology and design, the marina accommodates boats ranging from 16 feet to 300-plus feet in length.

One of the things that makes this marina so special is that it is installed directly above an active subway line. Because of this, drilling piles into the waterbed to hold up the docks was not possible. Using chain was also deemed impossible, due to the waves caused by the constant ferry traffic in the area. Now the floating docks are held in place using our Seaflex elastic mooring system, which does not interfere with the subway line below, and can withstand the constant waves caused by the ferry traffic.

Tim O’Brien explains the benefits of using Seaflex when asked about his promise that they will provide the calmest marina basin in New York City:

“Also, most marinas are built by banging pilings into the ground and hooking docks onto the pilings. This way, however, docks move around a lot. It’s also not ideal, when you’re building over subways for obvious reasons. So we used the Seaflex system that’s used around the world but not here. (…) Even at low tide the Seaflex is designed to be about 30 percent pre-tensioned, so there’s a fair amount of downward tension on the dock, and it creates a lot of stability and stiffness.”
