Launch Problem: How to Make a New York Pier Kayak-Friendly
The Green Team takes on urban kayaking.

It’s an almost surreal scene—gliding on the East River on a kayak, feeling the waves and the ocean wind while enjoying a sense of salty tranquility with the Manhattan skyline as your backdrop.
Recently, Mathews Nielsen Landscape Architects completed a feasibility study to determine if kayaking could be integrated as a possible amenity at our ongoing waterfront project at New York’s Pier 42. While the study is still in progress, our research to date has allowed us to expand our designer’s toolbox and has proved interesting enough to share. This post will give you the scoop on kayak launches, their design, and perhaps even inspire you to hit the water yourself.
Our Pier 42 project is located on the Manhattan side of the East River between the Manhattan and Williamsburg Bridges. The pier’s location is unique in that the shape of East River begins to curve north at this point, making a sudden turn at Corlear’s Hook. This shift in the river’s course (and the navigation channel) results in a “blind spot” for watercraft moving both up and down the river.

We consulted Nancy Brous, a member of the steering committee at the New York City Water Trail Association, to discuss siting a launch, with all necessary precautions in mind. Given Pier 42’s placement south of Corlear’s Hook, it was determined that a kayak launch would be best located away from the curve of the river there, preferably within a cove or an inlet, to mitigate the conflict between kayaks and harbor traffic. Thus, the most feasible spot was at the southernmost portion of the site, as illustrated below.

With the “launch space” designated within the 8-acre site, the design team then studied the types of kayak launches already in use in New York waterways—beaches, ramps, and floating docks. Determining which type to use is directly related to the bathymetry (submarine topography) of the selected site and its expected launching capacity. Beach launches, such as Dumbo Cove in Brooklyn, are preferred by most kayakers because it is easier and faster to load a kayak in shallow water.

Ramp launches, such as what we see at Hunts Point Landing in the South Bronx for example, have similar bathymetric requirements to those of the beach launches, but they have steeper slopes down to the water, resulting in reduced launch area. The third type, a floating dock (as seen at Pier 26 in Hudson River Park in Manhattan), is often found in spots where there is deep water or an existing bulkhead at the waterfront.
Due to the steep bathymetry along the shoreline of Pier 42, installing a beach or ramp kayak launch would require the excavation of adjacent upland area, resulting in a loss of space for parks and other program elements valued by the community. So, with limited upland area available for the proposed park, it was determined that a floating dock would be most suitable for this type of waterfront park.

Perhaps the most important aspect of siting a kayak launch is the hydrology, or the movement of water, around and within the site. Examining the existing tides (the vertical movement of water) and currents (the horizontal movement of water) at Pier 42, the team’s marine engineer, McLaren Engineering Group, performed a series of surface current studies as they relate to the observed daily 4-foot tidal change between low and high tide.
The study showed that the velocity of water adjacent to the pier was much stronger than anticipated. In the event of a flood tide, or the current created by water coming in at high tide, the velocity of the water could get as high as 3 knots (or 3.5 miles/hour). These velocities, coupled with wake patterns from busy harbor traffic, affect the control of watercraft (including kayaks) by creating localized turbulence and unpredictable surface current conditions throughout the day. While it is possible for experienced kayakers to navigate these velocities, beginning kayakers paddle at approximately 2 knots, so a kayak launch at Pier 42 would need to be designed for more advanced/skilled kayakers due to the surrounding hydrology.

Locating a kayak launch isn’t easy!
With each of these dynamic factors to consider, identifying the best position for a kayak launch is truly a site-specific process that depends on the project’s location, hydrology, and space available for the type options. While discussions of incorporating a launch at Pier 42 continue, there are still numerous places to get your feet wet around the city. So, before fall gives way to winter, get on that slice of heaven at one of these locations and experience New York City from a brand new angle!
