In the Netherlands, there is a general speed limit of 20 kilometers per hour for motorboats on the water. But in Friesland, you can hardly reach that speed on the inland waterways. The province enforces lower speed limits to protect the banks, nature, and other boaters. There are three speed zones you need to be aware of.

Maximum speeds by situation

The most important rule: the narrower and more congested the waterway, the slower you must go.

On the major canals, the speed limit is 12.5 kilometers per hour. These are the Prinses Margriet Canal and the Van Harinxma Canal, the main waterways of Friesland. This speed limit also applies in the concrete navigation channels on the major lakes, such as the Sneekermeer and Tjeukemeer. You can recognize the navigation channels by the red and green buoys.

Outside the navigation channels on the lakes and on most other waterways, the speed limit is 9 kilometers per hour. This applies to most of the Frisian waterways. On the open waters of the lakes, on the wider canals, and on the connecting routes between villages, you must adhere to this speed limit.

In harbors, within the built-up areas of villages and cities, and on narrow canals and ditches, the speed limit is 6 kilometers per hour. That’s comparable to walking speed. It feels slow, but on narrow waterways, higher speeds create waves that damage the banks and disturb waterfowl nests. On the Turfroute through Southeast Friesland, this 6 km/h speed limit applies along the entire route.

How do you know what speed limit applies?

Just like on the road, there are traffic signs along the water. A square white sign with a red border and a black number indicates the speed limit in kilometers per hour. When entering a harbor or village, you’ll often see a sign with a “6.” When leaving, there is sometimes a sign indicating the higher speed limit.

On the lakes, you can recognize the navigation channels by the buoys: red and green buoys that mark the channel. The speed limit is 12.5 km/h within those buoys and 9 km/h outside them.

A practical rule of thumb: if you’re unsure of the speed limit, slow down. Sailing too slowly is not a violation. Sailing too fast is. The water police actively monitor speed in Friesland. According to Rijkswaterstaat, speeding is the most common violation on the water.

High-Speed Zones

High-speed boating zones have been designated on a number of Frisian lakes where you are allowed to travel faster than 9 km/h. These zones are marked with yellow buoys and are located on lakes such as the Sneekermeer, the Heegermeer, the Slotermeer, and the Tjeukemeer.

However, these areas are not relevant to those operating a rented motorboat. High-speed boating is permitted only for small, fast motorboats with a displacement of no more than 1.5 cubic meters. Motor yachts, such as those found in the fleets of most rental companies, are not included in this category.

The high-speed boating areas are open from April 30 through September 30, from sunrise to sunset. A boating license is required, and the minimum age is 18.

Why are speeds lower in Friesland?

Friesland has made a conscious decision to enforce low speed limits. The main reason is to protect the riverbanks. Waves caused by boats traveling too fast erode the banks and damage the reed beds. This not only affects nature but also the nests of the water birds that live there. In addition, lower speeds ensure safety. On Frisian waters, motorboats, sailboats, rowboats, canoes, and stand-up paddleboards all share the water. With lower speeds, everyone has enough space to maneuver safely.

In practice

What do these speed limits mean for your boating vacation? In practice, there are few restrictions. An average rental motorboat travels about 7 to 9 kilometers per hour. That already puts you close to the speed limit on most waterways. The speed limits actually reflect the pace that’s typical of boating in Friesland: calm, relaxed, and mindful of your surroundings.

Take that speed into account when planning your route. The distance from Terherne to Sneek is about 8 kilometers. At an average speed of 8 km/h, you’ll get there in an hour. The distance from Terherne to Grou is similar. Longer routes, such as the 200-kilometer Elfsteden Route, can easily take 25 to 30 hours of pure sailing time at this pace, spread over several days.
