Time Out says
For a decidedly less urban paddling experience that’s still within the five boroughs, hop the ferry to Staten Island for free kayaking on Sundays. Wait for one of KSI’s Sit-on-Top kayaks (similar to traditional ones except you seat yourself in a depression on top of, instead of inside, the hull) at the company's new location at 850 Page Avenue. From there, you’re free to oar around a delineated embankment area in the bay for 15 minutes at a time, and are welcome to get back in line if you fancy a second voyage. Don’t worry about the waves—experienced rowers are in the water to help if you get tripped up.
