These are the most important rules for almost all Dutch inland waterways according to the INLAND WATER POLICE REGULATIONS; (BPR)

NOTE:
A large ship is a ship longer than 20m or a passenger ship, a fishing vessel, tugboat or  ferry.
The order of the rules is important !

A large ship that does not sail along  his starboard side of te water must give way to a small ship that sails along his starboard shore!

A sailing ship that also uses the engine the same time is seen as a motor ship
