The North Brooklyn Boat Club has released a new map “Get to Know North Brooklyn Waters” just in time for the warm weather kayaking season. The map includes a currents chart and points of interest along the East River and Brooklyn waterways. According to their website, “The currents chart indicates the times of slack water each day, or the point at which the East River shifts direction between the incoming flood and outgoing ebb tides that occur twice a day.” Check out their beautiful map here and get ready to hit the currents.
