The Ringvaart is an important waterway for commercial and recreational boats alike. A portion of it forms part of the sailroute from [[Hollands Diep]] to the [[IJsselmeer]], passable for ships with masts over 6 meters tall. There is also a connection to the Kaag Lake system ([[Kagerplassen]]), which extends to Leiden and beyond.

There are several canals within Haarlemmermeer itself, the main ones are Hoofdvaart (Main Canal) and Kruisvaart (Cross Canal). But these had initially no connection to the outside waterways, meaning that goods had to be reloaded at the ring dike. In 1895 a double [[Lock (water transport)|canal lock]] was built at [[Aalsmeer]], boosting the economy. In the 1950s this lock was closed and the canals are once again no longer used for shipping.
