A couple who was marooned on a Long Island river mudflat in a rented canoe cannot hold the rental company liable for the mishap, a judge has ruled.

“It is determined that getting stranded at low tide, whether on a river or on a sand bar near a beach, is an inherent risk in canoeing and arises out of the nature of the sport,” Suffolk County Acting Supreme Court Justice Denise Molia (See Profile) wrote in Ferrari v. Bob’s Canoe Rental, 6690-2009, granting the company’s summary judgment motion.
