The Kromme Rijn flows through nature reserves and these suffer from the many shipping movements, according to HDSR. A ban on motor boats is also safer for the large number of canoe and board paddlers who also like to use the Kromme Rijn. The water board will now announce the upcoming ban, because many residents along the river also have a motorboat. They now have a year to find a solution, such as purchasing an electric outboard motor.
