Erik Baard with HarborLab works to promote awareness on the water. He recommends kayaking as a group and always using a Marine Radio to check in with other crafts.

On Wednesday evening, about 10 kayakers collided with a ferry boat on the Hudson River. There were several injuries. The cause has not been determined and the investigation is continuing.
Baard says the incident should not erase Manhattan Kayak Company's great work, especially since the cause is not yet known. The kayak company resumed service Thursday evening. The ferry company is also cooperating with the inquiry.
Reports have indicated, when the kayak and ferry boat crashed, the setting sun could have cast a glare on the Hudson River.
