What is a Safe Speed for a Vessel?

April 30, 2025

Updated April 2025 Determining the right speed for your vessel is not always an easy task. Speed limits are not as ubiquitous on the water as they are on roadways, and much depends on your surroundings and the current environmental and meteorological conditions. Boaters are expected to accurately assess the situation at hand and adjust their speed accordingly.

At what speed should you navigate?

Boaters should always obey speed limits when available. Speed limits will often be posted on buoys or markers in the water, generally in km/h. The Vessel Operation Restriction Regulations also provide a list of speed limits for specific parts of various waterways in Canada. Several Canadian provinces have a blanket 10 km/h speed limit on vessels within 30 m of shore, which may not be posted but must nevertheless be obeyed.

The most important consideration when determining boating speed is the safety of those on the boat and in the surrounding area. Certain conditions may require slower speeds than the posted limit in order to ensure everyone’s safety.

What factors should be considered in determining a safe speed for a boat?

Determining a “safe speed” for a boat isn’t about hitting a specific number on the speedometer; it’s about operating at a speed that allows the operator to maintain full control, take effective and timely action to avoid collisions, and adapt to changing conditions.

There are many factors boat operators need to consider when determining a safe speed:

Visibility conditions (fog, mist, rain, darkness, etc.)
Wind conditions
Tides and currents
Vessel maneuverability
The amount of traffic on the waterway
Navigational hazards
Water depth

It’s important to remember that the faster a boat is moving, the longer it will take to come to a stop. High speeds can also make it harder to control your craft, particularly in adverse weather conditions.

How speed affects your wake

When boating, operators need to be mindful of the safety of the other people using the waterway as well as their own. Powerboats generate a wake as they move through the water, the size of which depends on speed and water depth. A large enough wake can cause smaller boats to capsize and be dangerous for people in the water.

Boaters are legally responsible for navigating in such a way that their wake doesn’t harm anyone or cause any damage.
